Added ErrorContext to give more context which action caused the actual error.

This added AuthState.errorContext: ErrorContext which holds information what was causing the issue. Most likely which method and (if available) the provided args.

Looks great. I see that you added an additional property to avoid breaking the API. Extending the existing error property would make it easier for usage. Either you have an error object or its null. If you have one you can find the message + details...

For me it would be ok in that situation to bump the major version and break the ABI...

Ideally we also adapt error object within that new component: #1476

Sound like a good idea. Also since now useAutoSignin() is merged to main, I'll try to scatch something. Give me a moment.

I've just adjusted as discussed. I've tried to find a sweet spot between do not introduce a new property but also do not break the current API tooo much.

Therefore: Error is not longer an Error class, it is an interface which has several properties also an Error class usually has, but not all (except name).

What was in the initial contribution kind is now source as it makes now more sense, I believe.
