Getting 500 Internal Server Error on a remote server only -- works fine locally.

[Cross-linking for reference: https://stackoverflow.com/questions/32809360/dropbox-core-api-500-internal-server-error-on-a-remote-server-only-works-fine ]

A few questions to help track this down:

- Does this occur for every account_info call you make for that user on the AWS server?

- Are the app key/secret and access token/secret the same on the AWS server as on your local machine?

Hi Gregory -- thanks for getting back to me!

To your questions:

- Does this occur for every account_info call you make for that user on the AWS server?

Yes, every time.

- Are the app key/secret and access token/secret the same on the AWS server as on your local machine?

Yes, they are. I have also tried re-running the auth flow from the server in question, and then using the "new" access token / access secret, with the same result.

Please let me know if this wasn't clear of if I can provide any more info. Thanks again!

EDIT: Also, happy to hop on the phone/skype/screen share/whatever, if it will help resolve the issue. Feel free to email me at matt < at > hellocompass.us to coordinate.

Thanks! In that case, can you make this small edit to the Ruby SDK to enable some additional debugging output? Just add this third line (with set_debug_output) after http is defined in the self.do_http def in the Dropbox module in dropbox_sdk.rb:

def self.do_http(uri, request) # :nodoc:

    http = Net::HTTP.new(uri.host, uri.port)
    http.set_debug_output $stderr

Then please run the failing method again and copy over the resulting output. Be sure to redact secret values (such as the app secret and access token secret, but please keep the keys showing).

Feel free to open an API ticket with it instead if you'd prefer to share privately:

Thanks again Gregory!

I did that, and threw the result on pastebin, here: http://pastebin.com/kaUTdNqk

NOTE: after adding the debug line and a trailing new line to the self.do_http method indropbox_sdk.rb, the line numbers in the stacktrace are off by 2, when compared to the unaltered dropbox_sdk.rb file.

Please let me know if I can provide any additional info.

Thanks!

EDIT: I got the same result using both token / token secret pairs (one that I generated and use successfully, locally, and one I generated on the server in question) 

Thanks! It looks like the issue is that you have an extra comma character after each piece of your tokens. I.e., your oauth_consumer_key has a value like "xxxxxxxxxxxxxxxx," instead of "xxxxxxxxxxxxxxxx". We'll look into fixing our parsing so that we don't error out on that, but to get it working on your side, just remove that extra ","s.

Wow -- can't believe I did that. Definitely a case of 'error between user and keyboard': had commas in the server config YML (but not in my local config), as if the data was a ruby hash rather than YML markup.

Thanks so much, Gregory!
