In the end I emulated tty using the following

script --return --quiet -c "az container exec --resource-group myRG --name myImageName --exec-command ./run.sh'" /dev/null

still seems to be an issue in 2024 @navba-MSFT

Getting this issue running against container app on an azure devops Ubuntu 22.04 agent

 az containerapp exec -n my-container -g my-rg   --command "./manage.py my_command"

Please ensure there is an alive replica.

@navba-MSFT - Any update on this? Seeing the same behaviour on the following setup, running on ubuntu-latest:

azure-cli                         2.37.0
core                              2.37.0
telemetry                          1.0.6

Extensions:
azure-devops                      0.25.0

Dependencies:
msal                            1.18.0b1
azure-mgmt-resource             21.1.0b1

The workaround from @gary-x0pa works, but presents me with a different problem.
