How to get full Stack Trace on Heroku

Question

My api is returning an error but, is not showing a full stack trace:

2018-04-20T12:32:00.673008+00:00 heroku[router]: at=info method=PUT [...] status=500 bytes=243 protocol=https

I don't know why I'm getting this 500, since it works at development. I guess is about some missing add-on on Heroku or something like this, but I cant know if I don't get the 500 stack trace.

I already have a config.log_level = :debug at my production.rb. Is it possible to see full stack trace at Heroku?

My project back-end uses Ruby on Rails 5.

From command line run:

heroku logs -n 200

after -n number of lines you need . check this out for more information.

I can access log by CL or web app, but the log is simply too poor. I have no details, so I dont know what is causing the error. Is there something that may be making the log so simple? ( as seen in the question, it only tell me that an 500 ocurred) – Agraphia

Please Add full trace – Tenorite

I've already added all the trace in the question :/ Only omitted some attributes (path, host, request_id, fwd, dyno, connect and service). Any of these matter in this case? The trace, again: 2018-04-20T12:32:00.673008+00:00 heroku[router]: at=info method=PUT [...] status=500 bytes=243 protocol=https – Agraphia
