Test results group by selection is ignored when a filter is changedThe Test Monitor test results table allows grouping results by property. When a user selects a group by property and adds a filter, the group by behavior is incorrect. Results are shown separately instead of grouped.
Workaround: Select a different property to group by and then re-select the original property to reset the table.

A limited number of variables may be visible in SystemLink OPC UA ConnectorWhen creating a new session from OPC UA Connector it is only possible to see the first 100 OPC UA Variables published by certain servers.
Workaround: Some OPC UA servers have a default number of variables to return if a number is not specified in the request. If this value is configurable, increasing it will return more variables to SystemLink.

Faulty system updates can cause multiple redundant refreshesClient systems that send continuous property updates, often fan or temperature related, may cause the server to execute a refresh job for each update. This may impact performance in extreme cases with multiple client systems.
Workaround: There is currently no known workaround for this issue. |

Test Monitor LV API may pass null for parameters instead of empty arrayLV API calls to the Update Step VI without setting the Parameters input, and under specific conditions, will incorrectly send a null parameter to the server rather than the correct empty array.
Workaround: There are two potential workarounds. 1) Set the Step Object Parameters to be non-empty, and then explicitly set the Parameters input to an empty array for each call of the Update Step VI. 2) Always use a branch of the original Step Object reference wire instead of the Reference out wire of the Create/Update Step VIs.

Webserver may accept requests with invalid basic auth credentialsSending a request with Basic Auth headers which are invalid and `insecureAccess: true` causes the request to be forwarded to the affected service anyway. This may result in malicious users accessing default workspace resources such as notebooks and reports. Workaround: There is currently no known workaround for this issue. |
