Identity Manager failing on Internal Testing on Kotlin App

[Asker Ali]

Hi there,

I’m a novice to mobile development, and i’ve been having this issue for a week now, i don’t know how to fix.

I implemented Identity Manager API for google sign-in in my Kotlin app. I have my own backend i send the ID tokens i get through this api, then i authenticate users in my backend. This flow works perfectly in debug mode/emulators on android studio. But when i publish it to internal testing I get the NoCredentialException . I’m signing my app using google and i added their SHA-1 to the SHA certificate fingerprints in my firebase settings. I can’t get past this error and all the info I’ve found so far was not very helpful. I’ve been stuck on this for days now…

Any help is appreciated,

Asgar!
