HTTPError at /complete/fiware/

[francucchi]

Hello,
I'm running dockerized images of wirecloud+nginx and keyrock (with OAuth2) and I'm having some issues probably related to gunicorn running in the wirecloud image.
Here's below the stack trace:

where 172.18.1.11 is internal IP address of wirecloud and 172.18.1.15 is internal IP address of nginx.

Any idea?

Thanks

Hi @francucchi!

It seems a problem on the KeyRock configuration/deployment. The stack trace is telling you that WireCloud received a 500 error (an internal server error) response from KeyRock when making the request to http://192.168.5.205:3005/oauth2/token.

Please, check the logs of keyrock for more details.

Hi @aarranz !
thanks for your reply.
Sorry for the delay in getting back to you but it took me some time to replace the keyrock docker image with a more updated revision available on github which has now solved the 500 Internal Server Error.
Unfortunately a new error is appearing after the authentication through keyrock:

I have already implemented the workaround for:

SESSION_COOKIE_NAME = "wcsessionid"
CSRF_COOKIE_NAME = "wccsrftoken"

but problem still appears.

Any idea?

Thanks again
