The APIM also becomes unresponsive after the failed pipeline (Management API becomes unreachable)

After deleting all APIs and attempting publish the configuration again, the pipeline completes with no issue.

Expected behavior

No 409 error are triggered when the pipeline is running against an APIM that was configured by the pipeline in the past

Actual behavior

It is not possible to publish changes to some APIs due to error HTTP error 409

Reproduction Steps

None

~~A rough summary of the APIM instance can be found here https://github.com/Azure/apiops/issues/135#issuecomment-1310804049~~

[Gabriel123N]

I ran the pipeline a few times in a row by reproducing the steps in 2nd comment and no errors were triggered.

Thank you a lot for your help once more!

[Gabriel123N]

I added the pipeline logs at the root of the repo. The configuration file is also present directly under the “apim” folder.
