As I remembered, this may relate to email address is not found in that User object which is valid in anonymous user. It will be great to return a User object with user id from firebase with empty or null value in email field.

Hello @g-ericso ! Have this issue been solved for today? I have faced the same problem..

[g-ericso]

Yes. it was fixed that last year. I don't remember exactly which field is causing the NULL pointer exception. However, it is a problem due to either username or email address was NULL for anonymous user. I thought a fix was applied. Let me figure it out more.

[ryzhovdv]

Thanks @g-ericso ! If it is applied, how to avoid this error?

Can you please give us more details or trace logs?

This bug was fixed in endpoints-management-java release 1.0.11.
Please make sure the customer's pom file includes the correct dependency version (https://cloud.google.com/endpoints/docs/frameworks/java/adding-api-management)

com.google.endpoints endpoints-management-control-appengine-all 1.0.11

Hope it helps,

[ryzhovdv]

Good day! When I changed endpoints-management-java version to the latest -1.0.11 the error have gone! Thanks! But the user argument at endpoint method is null when i get token for anonymous user on android app. When i get token for google account user on android app everything works! At firebase console Anonymous login is allowed and I see anonymous users and it's ids. Why it is not the case at appengine - don't know..
