@detienne20 could you please help to have a look at this issue~

[usrme]

Seeing the same error message as of yesterday, which is weird as the command has been in use for quite some time now... For some reason some template specs have the artifacts property defined and some don't, which trips up the underlying Python code.

@detienne20, despite #17890 being successfully resolved I am still seeing issue even with 2.23.0:

# az ts export --name {} --resource-group {} --version {} --output-folder .
Command group 'ts' is in preview and under development. Reference and support levels: https://aka.ms/CLI_refstatus
The command failed with an unexpected error. Here is the traceback:

The template spec in question does not have any artifacts defined:

I have this issue too. Happy for you to ping me internally if you want to see the debug output. I'm using CLI v2.24.2.
