I have an application that uses both Auth0 and Firebase.
Using Auth0.js, I followed the instructions here for changing delegation methodologies from getDelegationToken to client.delegation: Migrate getDelegationToken() to auth0.js v9
However, when I try to use the returned token for firebase login, I’m getting the error: “auth/invalid-custom-token:The custom token format is incorrect. Please check the documentation.”
For reference, here is the original (working) v7 code:
and here is the new (non-working) v9 code I’ve written:
“delegationResult.idToken” is what appears to be in the wrong format, but I don’t see any other value returned by the delegation endpoint to use.
Any help would be greatly appreciated!
