az-cli fails with 'NoneType' object is not callable

[Dmitri Beltjukov]

We have a job, that cleans out container registry. If you run these commands locally, everything seems to work fine. The pipeline itself was fine, no changes were introduced. Today it just stopped working all of a sudden.

- az account set --subscription "Staging Subscription"
- az acr run --cmd "acr purge --filter 'b2b:.*' --untagged --ago 30d" --registry "staging" /dev/null
- az account set --subscription "Production Subscription"
- az acr run --cmd "acr purge --filter 'b2b:.*' --untagged --ago 180d" --registry "production" /dev/null

The trace as follows. Any ideas?

+ az acr run --cmd "acr purge --filter 'b2b:.*' --untagged --ago 30d" --registry "staging" /dev/nullERROR: The command failed with an unexpected error.
