Docker response to Reverse proxy:
2018-06-19T07:38:02.253042500Z IPADDRESSHERE - - [19/Jun/2018:07:38:01 +0000] "POST /api/0/projects/myorg/myproj/releases/1.1.4-sourcemap-test-461/files/ HTTP/1.1" 201 498 "-" "sentry-cli/1.29.1"
2018-06-19T07:38:02.681132200Z IPADDRESSHERE - - [19/Jun/2018:07:38:02 +0000] "POST /api/0/projects/myorg/myproj/releases/1.1.4-sourcemap-test-461/files/ HTTP/1.1" 201 496 "-" "sentry-cli/1.29.1"
2nd response indicates 201 (created) but results in failure when it reached the reverse proxy, the only apparent difference is the column after the response code.
Is it possible this could be the size (496 bytes instead of 498) and that the response is missing something like EOF?
I would like to find a way to actually capture the response from Sentry to see what is actually returned.
