Known Issues and Limitations

Table 2. Known Issues and Limitations
The following known issues and limitations exist.
Description	Tracking ID
In a trend chart, if you add a tag that is identical to the one that is already plotted but the case of the tag name does not match the case of the tag name in Historian, a straight line appears in the trend chart. To resolve this issue, modify the tag name to match the case of the tag name in Historian.	DE123833
During Operations Hub installation, when you provide the tenant user ID, the following conditions apply: If you are installing Operations Hub for the first time, do not provide StudioAdmin as the tenant user ID because it is used by Operations Hub. If you want to use a shared Proficy Authentication (UAA) to work with Operations Hub, do not provide the user ID of an existing user of the UAA instance. If you do so, the installation fails. If you are installing Operations Hub after uninstalling it without purge, do not provide a tenant user ID that matches any previously used user ID (including any previously used tenant ID). This is because after you uninstall Operations Hub without purge, previous Operations Hub users (along with tenant administrators, their groups, and privilege assignments) still exist in the database.	DE123770
When you create a data source, you can provide a certificate only in the base-64-encoded format. A DER-encoded certificate is not supported.	DE116706
Operations Hub uses Kafka, which generates a large number of logs in the following location: C:\tmp\kafka-logs\. To avoid consuming too much space for these logs, we recommend that you periodically delete the logs, especially if the system has low disk space.	N/A
If you encounter intermittent responsiveness issues with the Operations Hub runtime environment when using the Safari browser on your mobile device, it is recommended that you use the Chrome browser instead.	DE131011
When adding environment variables to Windows System Variables, be aware that environment variables are case-sensitive. If your environment variables in Operations Hub do not match the case of the ones used by the target Historian Server, the data source will fail when tested. Be sure that you use the same case when configuring data sources in Operations Hub. A data source target in Operations Hub should match the case in the environment variables, as the variables are case-sensitive.	DE130896
Historian REST response time increases exponentially when there are over 30 users logged into Operations Hub accessing an End app that utilizes Historian REST queries.	DE134904
When using Safari 13+ on iOS, trend card functionality like adding tags to the trend, favorites, and annotations perform inconsistently. The workaround is to use the Chrome browser on the iPad.	DE136597, DE149433
If a Historian data point being trended transitions to a bad quality (such is the case when a collector goes down or loses communications), the trend card displays a flatline for the last known good value. If you experience one or more flatlines in your trends, and all the various requests from the same source, you should check the communication chain for an issue with Historian, a collector, or a SCADA driver, for instance.	DE138128
There are currently some page printing issues. For instance, if you have iframe that spills over to a second page, that can cause an issue.	DE146462
The `uaa-provisioning.log` file generates in a new folder if the location path provided during Operations Hub installation contains a space in it. For example, C:\Custom Logs.	DE148827
As a workaround to address VC++ (x64) failure, follow these steps to install Task Client on Operations Hub 2.1. Uninstall the VC++ 2015-2019 Redistributable (x64) version installed with Operations Hub 2.1. Open the Workflow install media, navigate to the `\Installers\Resources\Microsoft\2015_2019` folder, and run the `vc_redist.x64.exe`. Open the Services console dialog and restart these services: GE Operations IQP PostgreSQL Database GE Proficy Authentication PostgreSQL Database Install Workflow Task Client. Install the VC++ 2015-2019 Redistributable (x64) version that got installed with Operations Hub 2.1.	DE161643
If the Data Distributor service started at a time when the datasource was offline, reload the end application.	DE158762
For REST connection, if you enter an IP address instead of the hostname in the Auth URL field, it results in a 404 error. You must add the IP address to the list of supported subdomains/zones. To do this: Browse to the location directory on the machine where Operations Hub is installed: `..\ProgramData\GE\Operations Hub\uaa-config` Open the `uaa.yml` file in a text editor. Search for `hostnames` in the file, and enter the IP address. Save and close the file. Restart Proficy Authentication for the changes to take effect.	DE153631
When importing a model containing a second CIMPLICITY namespace table, it overwrites the values in the first namespace table. Workaround: Combine the server and namespace information from the two namespace tables into one namespace table, and then import the model again.	DE47669
The inline mimic write operations performed in Operations Hub are indicated as successful even if the entries did not meet the criteria of these CIMPLICITY attributes. WARNING_LOW_N WARNING_HIGH_N ALARM_LOW_N ALARM_HIGH_N The values do not get updated to the CIMPLICITY point control panel.	DE156030
Error message does not appear when you perform a write operation on a CIMPLICITY tag value that is outside of a given range.	DE157698
If you select Acknowledge All in Operations Hub to acknowledge 5000 iFIX alarms, an internal error occurs in the iFIX application.	DE161742
Only a single instance of the CIMPLICITY HMI Webspace widget per app is supported. If using multiple instances of webspace widgets across multiple pages, you may encounter access error messages when navigating between pages that contain webspace instances. After confirming the message, the widget loads as expected.
The `typeName` parameter in the custom widget’s `manifest.json` file does not support special characters.	DE162893
For Operations Hub 2022 release, Proficy Authentication server validation fails while installing Workflow Task Client. As a workaround to fix this issue, please refer to Resolving Proficy Authentication Issue During Workflow Task Client Install.	DE174960
In Operations Hub 2022.4.1, line chart legend is not updating based on the updated parameters for the chart. The line chart always shows only the initially fetched data for a query.
If an App uses multiple nested containers and a large number of queries, it impacts the page load performance.	DE170644
Events do not trigger after they work properly for a while. Restart the following services to fix the issue: GE Operations Hub IQP Zookeeper GE Operations Hub IQP Kafka GE Operations Hub IQP Tomcat Web Server	DE178533
MQTT slow response impacts page load performance.	DE183156
While using the trend card on iOS 15 Safari browser, the tags in a drop-down menu are not displaying properly. This occurs when there is more than one page in an App.	DE184797
The following issues are noticed in Operations Hub on Android device: Unable to select data sources from the Add Sources dialog to configure a trend card. Unable to navigate between multiple pages in the End App.	DE184895, DE184901
If you create a display condition for a widget (or container), the widget (or container) is hidden regardless of the condition not being met. Condition always defaults to true at runtime.	DE184491
Some times on a trend chart, the AXIS LOW limit is not being returned if the duration of the trend is modified. The values are auto scaled based on the property data for the current duration. For example, consider a tag with a low/high of 0-100, and with actual data values ranging from 40-60. In this case, when you change the duration of the trend, the y-axis for this series might switch to show 35-100, instead of 0-100. Except for the low-range value returned by Historian, all the other data values appear on the trend. Workaround: On modifying the trend duration, go to each tag and reset its AUTOFETCH LIMITS. To reset, first turn off the toggle, and then turn it on to fetch low/high limits appropriately.	DE185861

Fixed Defects

Table 3. Fixed Defects
The following fixed defects have been addressed with this version of Operations Hub.
Description	Tracking ID
Previously, exporting an asset model remained unsuccessful with errors. Upgrading to Operations Hub 2022.4.1 resolved the issue.	SF01008750, SF01011692
Previously, configuration issues occurred while upgrading from Operations Hub 2.1 to 2022. Re-uploading the service provider’s `metadata.xml` file resolved the issue.	SF01021840
Previously, if source values came from another source/dropdown for `GEDateTimeRangePicker`, then the values were not being passed down to the target globals. This issue has been resolved	SF01021950
During app import, the system only checks for duplicate conflicts due to same name. The system does not highlight if a conflict item contains a renamed artifact. Choosing to replace a conflict item in such scenarios may lead to binding loss. This message is highlighted in the confirmation screen for app import.	SF00997849
Previously, custom dashboards stopped working due to data source related error. This issue has been resolved	SF00998439
Previously, MES dashboard logos disappeared after a reset. This issue has been resolved by providing a fix to allow anonymous access to the image URLs.	SF00997558
