[IsHafid]

i ve been using pac pcf push --publisher-prefix dev to push my code in the environement for the past 4 months , and it was working flawlessly ,and today some i m getting this error without doing any changes or updates :

MSB0001: Internal MSBuild Error: The switch name extracted from either the partially or completely unquoted arg should be the same.
i don't understand the error and i can't find a solution to it

Getting the same error. With the same command

It looks like there may be a breaking change with the msbuild command executable on the machine, and how the pcf push is calling msbuild.

Please open a support ticket where we can ask for logs to verify.

Yes error for me as well. Worked as expected until Wednesday and started seeing this issue from yesterday. pac pcf push --pp solutionprefix is failing.

So far, I was not able to repo it. It might be good to open support ticket and reference this GitHub issue for faster routing. You can also attach full log files to the support ticket.

+1 I'm also having this issue - please let me know how I can assist with logs

For now I downgraded to 1.27.6 and it's working again.
