Error did not have any matching .app or .ipa bundles

hi i have this error message when i click the button ‘start session’:

Failed to create session. An unknown server-side error occurred while processing the command. Original error: /Users/xxx/Downloads/TEST.ipa did not have any matching .app or .ipa bundles. Please make sure the provided package is valid and contains at least one matching application bundle which is not nested.

what can it be?

you have this error in Appium Inspector?

yes exactly. If I insert the .app file, it works while with .ipa it does not.
