Create a folder with special characters will get empty response

I tried the following operation and got empty response.

I can't distinguish between "Invalid name" or "Server temporary error"

Is it possible to return detailed message which can indicate invlid file name ?

curl -v -X POST https://api.dropboxapi.com/2/files/create_folder_v2 --header "Authorization: Bearer accesstoken" --header "Content-Type: application/json" --data "{\"path\": \"/�}�֌W\",\"autorename\": false}"
Note: Unnecessary use of -X or --request, POST is already inferred.

Thanks for following up. I wasn't sure if that was the actual payload the app was sending, or if it got mangled when posting to the forum. I'll work on reproducing this with that and ask the team to fix the error handling.

I can't promise if/when they might be able to work on that though, so I recommend also updating your app's code to be able to handle server errors like this.

A 500 error like this indicates something failed on the Dropbox API servers when processing the request. Unfortunately there isn't a way to retrieve more information about the failure via the API, but we can look into it for you.

To help us do so, can you share more information about how to reproduce this? It appears to be due to the path value you'e supplying, but that value appears malformed in your post here. Can you share exactly what data you're sending that results in this error?

The folder with malformated name is exists in one of our customer's NAS device, then our applicatoin on NAS tried to create that folder on his Dropbox but got 500 Internal Server Error.

Unfortunately, I can't tell why he created that name, but you can reproduce the error with the command as I posted previously.

I think 500 Internal Server Error can be retried and recovered normal later, but in this case it's not so our application kept loop retrying

If it can return any error other than 500, that will help. Thank you.
