URL Fetch Exception

[Gabriel Axel]

Greetings,

Starting today I am getting the following error in a Standard Java 8 app:

com.google.apphosting.api.ApiProxy$UnknownException

An error occurred for the API request urlfetch.Fetch()

and it kept repeating until I shut down all the instances of the app in that project, but a few hours later the error reappeared until I shut down all instances again. The same app deployed to a different project did not experience this at the same time, nor did I experience it locally.

This happens when I use Google OAuth2 client library to verify a token received from the web client in com.google.api.client.googleapis.auth.oauth2.GoogleIdTokenVerifier.verify()

Project number: 875106233913

Error ID: CICFyM7BtLGgswE

Any help in resolving this will be much appreciated.

I figured the use of URL Fetch was a remnant from when the app used the Java 7 runtime and is no longer needed in the Java 8 runtime, so I switched from UrlFetchTransport to NetHttpTransport which works fine so far.

Now I started getting this for Blobstore calls. I opened an issue: https://issuetracker.google.com/issues/117343597
