steps:
- task: MSCRMImportSolution@12
  displayName: 'Import Solution'
  inputs:
    crmConnectionString: 'AuthType=Office365;Url=$(Url);UserName=$(User);Password=$(Password)'
    solutionFile: '<something something>/solution.zip'

Exports work but imports don't. Any help where the problem could be?

@randombyte-developer are you able to run the pipeline in debug mode and share more logs?

Sorry for the late reply.

Idk why but it works now. I didn't change anything. Maybe something in the backend wasn't working correctly at that time. I'll let you know when I get this error again.
