We are deploying the Azure Infra using bicep templates and azure cli commands from a long time. Never experienced this error but when I tried to do upgrade of bicep using the command az bicep upgrade, I got this error.

Even the command az bicep version giving the same error suddenly in my system.

what is the root cause of this error and how to resolve it?

Solution

  • When we do run the command in any terminal az bicep upgrade and terminate the operation without completing the upgrade fully, then we will be getting this error.

    With reference to this MS Doc of Azure Bicep, if you get the issues like above on az bicep commands, do uninstall and install it clearly.

    1. Uninstall the bicep modules with the command az bicep uninstall.

    2. Close the terminal or command prompt and reopen the terminal or command prompt or vs code as administrator and then run the command az bicep install to reinstall the bicep fully.

    C:\Users\kamali>az bicep install
Installing Bicep CLI v0.29.47...
Successfully installed Bicep CLI to "C:\Users\kamali\.azure\bin\bicep.exe".

    You will wait for the full operation completion and then check the installed version using the command az bicep version.

    C:\Users\kamali>az bicep version
Bicep CLI version 0.29.47 (132ade51bc)
