notarytool throws Unexpected end of JSON input

[drale2k]

I was not able to make it working using notarytool, the default, as it was always throwing the following error during the notarization step:

Run lando/notarize-action@v2
Archiving Application
Notarizing with notarytool
Error: Notarization failed with an unexpected error: Unexpected end of JSON input

I got it working by switching the tool to altool:

...
with:
  product-path: dist/myapp.app
  appstore-connect-username: ${{ secrets.APPLE_ID }}
  appstore-connect-password: ${{ secrets.APPLE_ID_PASSWORD }}
  appstore-connect-team-id: XYZ
  tool: altool

Leaving this here in case anyone bumps his head for 30 mins like i did.

I had the same problem today but I just had a pending signature on my apple developer account - about some policy change or whatever. After I signed it, it worked well. Unfortunately, by the time I ran this action again with the verbose option (which you could try as well) I already signed the said document, so I'm not sure where the json error came from. Is it a parsing error in the action, or the notarytool CLI itself? I'm not sure.

Changing to altool doesn't really solve anything, since it's already deprecated.

For me I was first missing the 'teamId" when I ran build, and then the "ascProvider" property when I ran package, adding them at each step to await notarize({... (inside notarize.js) seemed to work

Now that altool can no longer be used i had to go back to notarytool and i am again running in to the same issue. Any workaround? None of the above options are relevant to me

I turned on verbosity, and it seems the error is caused by the Apple API returning a 403

Turns out my Team ID changed for whatever reason. Verbose logging made that clear.
