Cyclops always return 404 when posting an error? Why ?

[antonbabenko]

I am trying to integrate Cyclops installed locally on autoscaling instances to proxy requests to sentry.

I have tried to have Cyclops running with and without nginx (according to documentation), also tried with and without mysql access to sentry set in cyclops.conf. No difference. Same error... scroll further.

Relevant part of cyclops.conf:

SENTRY_BASE_URL = 'sentry.myhost.com' # tried with http:// prefix also
PROJECT_KEYS = [(3, '1c0521e44ea943d5b6cd4cd465746337', '260a53dc6441420985ae34f14b63b567')]

Since I am using https://github.com/getsentry/raven-php to log errors I specify such endpoint: http://user:pass@127.0.0.1:9100/3 , which looks correct (user:pass are required by the library).

This is the error:

anyone ? /cc @heynemann maybe you know where to dig ?

I've run into a similar issue (except with the Python client) and found that it always 404's for the first call after the Client class is instantiated, and then for random (but not all) calls after that. Also notice that the first call returns both a Sentry UUID AND a 404 from Cyclops. Think this may be async issues?

>>> client = Client('http://xxx:xxx@127.0.0.1:9000/2')

I have the same issue too :/
Did you find a workaround for that one ?
