Dropbox API 409 error randomly

[JiaLiPassion]

I am using access token to access dropbox API to `list_folder`, `download_file`, `downloadfile_zip`.

And the result is

1. https://api.dropboxapi.com/2/files/list_folder api can sometimes return the results, I tried 10 times, 2 times get the results, the other 8 times with the exact same request parameters will get 409 {"error_summary": "path/not_found/.", "error": {".tag": "path", "path": {".tag": "not_found"}}} error.

2. download_file and downloadfile_zip always return 409 error.

Is there any limitation for the API with the access token?

The API does have a rate limiting system, but if it needs to reject a call for rate limiting, it would return a 429, not a 409.

1. If it appears the API is incorrectly returning this error, please share the request and response, showing both headers and bodies, so we can take a look. Be sure to redact the access token though. Feel free to open an API ticket instead if you'd prefer to share privately.

2. Please check the response body for an error message. As above, if it appears this isn't working properly, please share the details.
