Nigel™ AI LabVIEW Code Generation Takes Too Long or Fails

Issue Details

Nigel AI is taking much longer to generate LabVIEW code than it did for similar kinds of requests previously.
Nigel provides a failure message in the chat when I try to use it to generate code. Nigel may say something like “LabVIEW Coding Agent tool failed...” but as this is an LLM generated response, the exact wording will vary. 

Solution

This is a known issue that NI is currently working to resolve.

As a workaround, set the Nigel setting “Allow Stored Output” to False/Off. 

You can do this by going to the menu. Then choose More>Settings> Allowed Stored Output.
