Does anyone encounter the problem on Endpoints with authentication?

[Colin Su]

I encountered a problem recently, and it will let us couldn't testing our Endpoints API locally, but production is still okay.

We didn't change any code at that time (maybe), but it just become not working anymore.

The problem is while I'm accessing endpoints API with authentication by OAuth2, it will shows this exception and broke:

but without authentication it works fine. Anybody got some idea about this?

What version of the local development server are you currently using?

I have absolutely the same problem. Tried both 1.8.7 and 1.8.8 SDK on Mac 1.9. All HTTP requests with OAuth token to Endpoints fail with that decoding error. 

This is with 1.8.8 Python SDK

RuntimeError('UnicodeDecodeError(\'utf8\', "id_token verification failed: Can\'t parse header: \\xc9\\xad\\xbd", 52, 53, \'invalid start byte\')',) 

The whole mess is caused by Encode() in api_server.py line 162. It adds some invalid symbols at the beginning and at the end. But HTTP request and token look OK. And actually code haven't changed for me. For me 2 things changed before this error started to appear:

1. I migrated code to Git repository

2. I updated to 1.8.7

3. I updated to Mac 1.9

And now I have no idea how to get rid of this error.

[David Neale]

I'm getting this on version 1.8.8 of the SDK.

[Colin Su]

I tried both 1.8.7 and 1.8.8

[Ilya Nesterov]

Just checked 1.8.8 on linux. Works fine. I was able to reproduce your error using 1.8.7 version. so feel free to update

[Ilya Nesterov]

My bad. 1.8.8 didn't fix the issue. Here is a tested patch https://code.google.com/p/googleappengine/issues/detail?id=10285
