I've tried your sample code and the issue doesn't reproduce for me, so it may be specific to some aspect of your environment or account.
That being the case, to help us track down these specific failures, please open an API ticket here and share the following:
- Have you made any modifications to the Dropbox SDK? If so, please share them.
- Please include several 'X-Dropbox-Request-Id' response header values for several responses with the error shown here.
- Please include the IP address used to make the requests that resulted in the errors identified in the previous item.
Thanks in advance and apologies for the bother!
Hello Greg-DB,
I have reproduced the issue today and submitted the request as you suggested. It was actually pretty hard to reproduce it today, it took 1432 requests. I'll also post the data you asked for here:
- Have you made any modifications to the Dropbox SDK? If so, please share them.
- no changes
- Please include several 'X-Dropbox-Request-Id' response header values for several responses with the error shown here.
- [X-Dropbox-Request-Id]=[5540b28dca5e40c1aa5ecde595c983a5]
- Please include the IP address used to make the requests that resulted in the errors identified in the previous item.
- (I won't rather post it here, but it is included in the ticket :D)
Thank you for your help.
