Error 500 on /2/files/upload_session/append_v2

[Vikkonst]

Hello!

We have random error 500 when we tryed upload files.

What reason can be?

[2020-02-17T22:51:06+03:00] ERROR '***' upload have been ended with error: 'Request url 'https://content.dropboxapi.com/2/files/upload_session/append_v2' method 'POST' failed, response code '500', error: '''

A 500 server error should indicate the call failed because of an issue on the Dropbox servers. Can you share a few sample 'X-Dropbox-Request-Id' response header values for these failures? That should help us track it down. Thanks in advance! 

[Vikkonst]

Dear Greg.

Unfotrunartly now we can't send you 'X-Dropbox-Request-Id'. We will add logging of ''X-Dropbox-Request-Id" and add here tomorrow.

At this moment I can send only logs when we were get error codes:

Also we were get one more error:

[2020-02-17T23:26:27+03:00] DEBUG Request 'https://api.dropboxapi.com/2/files/get_metadata' with 'POST' method
body '{"error": "Internal Server Error"}'

Timezone is +3 MSK.

Do you have rate limit for APIs?

[Greg-DB]

Yes, the Dropbox API does have a rate limiting system. (That's not what's happening here though. If an app hits the rate limit, the Dropbox API would reply with a 429 error status, not a 500.)

Anyway, we'll try to look into this based on the timestamps, but please do share the request IDs if possible. Thanks!

[Greg-DB]

We're looking into this, but we'll need some request IDs to be sure we're identifying the right issue(s). Were you able to add the logging? Please share some request IDs for some failures, ideally from today. Thanks!

[Vikkonst]

Thank you!

Adding IDs to the log in progress. We will write here when it will be done.

Please check.

Waiting your answer.

[Greg-DB]

Great, thanks, that's helpful. I'll follow up here once I have an update on that for you.

Also, if you're still seeing an issue on get_metadata, please share some request IDs for that as well. Thanks!

Great, thanks for the information.
