Crashlytics: Unable to package source due to error

Question

I am setting up an Xcode Bot to automatically upload and distribute my beta app. I have setup a mac with macOS Server and Xcode activated and am able to build and export an IPA manually just fine. The Xcode Bot I created also archives and exports an IPA with no problem.

However, when I try to run the Crashlytics submit script in the Xcode Bot's post triggers, the uploading fails. But if I save the bot generated IPA and manually call the Crashlytics script via Terminal, it uploads just fine. It seems that only the Xcode Bot fails to submit to Crashlytics.

I have all the correct certificates installed on the server Keychain and everything works fine for manual archive/export both in Xcode and using the Xcode Bot's generated IPA.

Here is the log from Xcode Bot:

Been pulling my hair out over this all day, hoping someone can shed some light on this problem.

Ok so turns out you need to run the app on a device directly from Xcode on the server machine so that Xcode will automatically generate all the appropriate XC iOS provisioning profiles. Apparently the Crashlytics script will re-package the IPA and need valid provisioning profiles in order to do so. I think the Xcode Bot generates an IPA but it is not fully code signed until you save from the bot results, instead of just running from a bot post-trigger.

If you go to the developer.apple.com portal and look under Provisioning Profiles you should see something like this:
