The same problem started last Friday for us on the following extension az extension add -n rdbms-connect --allow-preview=true running on a Windows-latest agent. One thing I noticed today after getting one of our stages to run correctly was that the Python version on the agent is different.

For our current pipeline, we invoke this stage a couple of times, so it uses the same exact code. Below is one of the stages that was completed correctly without the warning error.

Below is a future stage in the pipeline that failed with the same code but a different Python version.

@ampandres It's not accurate to call it the same problem without seeing the error message. 😉

You don't provide the error message. I guess your issue is the same as Azure/azure-cli-extensions#8264. I've reported to rdbms-connect owner.
