400 Client Error: Bad Request for url: https://api.dropboxapi.com/2/files/create_folder_v2

When you get a 400 error like this, be sure to print out the response body, as it should contain a more specific error message indicating what the issue is. If you need help with that error, please print it out and share it.

Also though, I notice that you're importing and using both 'dropbox' and 'requests', and you're using 'requests' to call the /2/files/create_folder_v2 endpoint yourself. We recommend using the official SDKs, such as 'dropbox' whenever possible though, and it implements native methods for the endpoints for you, so you don't need to use a network client directly, like you are with 'requests'. Specifically, instead of calling /2/files/create_folder_v2 with 'requests', you can use the provided files_create_folder_v2 method on the Dropbox class.

I notice you are using the 'Dropbox-API-Select-User' header; that's also available natively on DropboxTeam via the as_user method, which would then give you a Dropbox object which you can then use to call files_create_folder_v2, etc.
