Command-not-found handler shows up at the wrong time

[isra-fel]

Description

In the above screenshot, ARM returned an error that the resource group cannot be found, but somehow the logic of Discoverability was triggered. A meaningless and incorrect warning message was displayed.

Expected behavior

The warning message does not show up.

@isra-fel , could you explain further about this issue?

[isra-fel]

@dingmeng-xue , I've updated the title and description.

Can it be fixed in this release?

[isra-fel]

Not sure. We haven't found the root cause. Besides, it only affects some parameters in some autorest-based modules.
I plan to investigate it in this release, if any time left after WAM.
