Apple/fastlane submit for review action failing with unclear error message about privacy text

Question

I am following fastlane's default configuration conventions for a React Native project. That is to say, my project structure looks like (e.g.):

/ios/fastlane/metadata/en-GB

with the en-GB subdirectory containing the following files:

description.txt
keywords.txt
name.txt
privacy_url.txt
release_notes.txt
support_url.txt

Everything was working perfectly until I tried to internationalise.

Now, when fastlane's upload_to_app_store() (aliased with deliver()) runs in my CI/CD pipeline, it fails and I see the following error:

The provided entity is missing a required attribute - You must provide a value for the attribute 'privacyPolicyText' with this request - /data/attributes/privacyPolicyText

I already have privacy_url.txt in there which was previously sufficient.

Answer 1

The thing that fixed it was adding a apple_tv_privacy_policy.txt (just containing a URL pointing to our privacy policy) file to the en-GB subdirectory.

Weird, given that the Fastfile was working completely fine before without any sort of privacy policy for TV. Very frustrating error message!
