500 internal Server Error https://api.dropboxapi.com/2/files/list_folder/continue

I've using the following endpoint to retrieve files and folders:

https://api.dropboxapi.com/2/files/list_folder this returns 2000 entries and then get hasmore = true and the cursor. I then user this for the following endpoint :

https://api.dropboxapi.com/2/files/list_folder/continue

Everytime it returns internal server errror with no error detail. Can you help?

Thanks

Hi Cynthia, thanks for the report! Can you share a sample X-Dropbox-Request-Id response header value from the error response? Thanks in advance!

Hi,

I ran it again and since this post it comes back with this:

"The server has either erred or is incapable of performing the requested operation."

and this is the X-Dropbox-Request-Id: af74e496fa3618b6ec154ecc80d07387

Thanks

Greg-DB

Thanks! We're looking into it.

Do you know if there is any update on this please?

No, unfortunately, I don't have an update on this yet.

Hello! I am experiencing this same issue. Have there been any new developments?

Here is the id for one of the failed requests:

X-Dropbox-Request-Id: 528053bb29e10543840c056013341e54

Greg-DB

I don't have an update on this yet. I'll reply here as soon as I do.

Hi Greg,

Is there any update on this? The reason I ask is that the API v1 endpoints are going to be closed off June 28 2017 and it looks like this endpoint has some issues. If there is no solution is there a reliable work around?

Would processing each folder and its content be a reliable way?

Many thanks

Greg-DB

No, no update on this right now. I can't promise if that would work as a workaround, as each case may be different, but it may help.

volkeru

Since yesterday I have the same error on a directory containing about 5300 files. The day before everything worked fine. This is a big problem!!! How can I solve it?

volkeru

Sorry i had forgotten:

x-dropbox-request-id: 411bff0079c4fb574ef5b275949d594d

Greg-DB

Thanks for the request ID volkeru! That one happens to be a different issue than the one originally reported on this this thread, but it is also a known issue we're working on.

volkeru

Thank you for the answer! I just solved the problem in a VERY strange way! I renamed the folder in the Dropbox web interface from "TitaniumBackup" (which initially caused the problems) to "TitaniumBackup_" and then to "TitaniumBackup" back again. After renaming the folder twice everything now works again. But all 5000 files are being synchronized again, which takes more than 24 hours. Same as if I had deleted them all. This is really strange and obviously a thing you should work on... ;-)

attic

Also experiencing the 500 error, please let me know if this is the same issue or something new and hopefully an idea of when we could expect a fix?

x-dropbox-request-id:1aad2bb340a5f060d4890c5a1185a8ab

Greg-DB

Thanks for the report attic! That's the same issue as the one volkeru reported. We're working on it.

aaronboodman

Can you please give some indication of how long you expect this to take? We need to decide whether to workaround or not.

Greg-DB

I don't have an ETA for a fix right now. I'll post here once I have an update.

attic

FYI, my problem seems to have been resolved/fixed as of Wednesday, January 18th. Thanks for helping to ensure it got fixed!

Greg-DB

Thanks for confirming that, attic. Yes, the issue that volkeru/attic reported should be (mostly) resolved now. You may see some more, that we're working on fixing, but the rate should be much lower now.

jackolicious

Hi there, also seeing this happen repeatedly with no way to get around it.

Running:

files_list_folder('', recursive=True,include_media_info=True)

Then getting:

dropbox.exceptions.InternalServerError: InternalServerError('b1b9642f8210d246a2654454721d6469', 500, u'')

Any help would be greatly appreciated!

Greg-DB

Thanks for the report! We're still working on these remaining errors.

thedeck

Hello,

I'm experiencing the exact same symptoms while calling list_folder/continue.

X-Dropbox-Request-Id: 5f1b4cdc32283d77ee8f6fecb42597f0

Any ETA on the fix ? the v1 end date is coming fast.

Thanks !

jackolicious

If it helps, I was able to rectify the problem by:

iterating manually over all folders (instead of the recursive list)
finding the folder (or folders in my case) that would cause a 500 error
delete the folder(s) (send to dropbox trash)
once the complete iterative test is able to be run, restore all folders from dropbox trash
tada! the recursive list_folder works again.

:thinking:

thedeck

Thanks for the info. Unfortunately it's not really a possible workaround for my usecase

Greg-DB

Thanks for checking in, thedeck. I don't have an update on that one yet. I'll follow up here once I do.

And thanks for the information, jackolicious. For reference though, while the errors from different people on this thread are reported the same way to the API clients (i.e., a 500 error), they may be caused by different issues on the backend, so the workaround may not work for everyone.

volkeru

As I stated earlier in this thread it's not necessary to delete files or folders. It's sufficient to rename the folder that is affected by the problem to a different name and rename it back to it's initial name.

sfbrad

My https://api.dropboxapi.com/2/files/list_folder and the first 257 https://api.dropboxapi.com/2/files/list_folder/continue requests all return a valid response, but on the 258'th list_folder/continue, I get a 500 erorr with an empty response body. At this point, I have downloaded 470,090 file entries and an additional 38,878 folder entries.

Is there some limit (500k?) to the number of entries that can be returned via a single cursor?

Greg-DB

Hi sfbrad, no, there's no entry limit for a cursor. This error just indicates something happened to go wrong for that particular call. If you share a X-Dropbox-Request-Id response header value, I can look this up for you.
