Problem with GetMetadataAsync
Hi, I'm trying to test for the existence of a folder so as not to repeat myself. My understanding is that you use GetMetadataAsync and treat the folder as not there if you get an exception. (1) I'm ...

Dropbox StaffThanks for following up. You shouldn't be getting 'not_found' for a path that already exists, but if you are calling to get the metadata immediately after the item is created (e.g., in the case of a duplicate in your input list), there is a chance that can happen. The CreateFolderV2Async method (as well as others, such as the upload methods) return the metadata for the new item, so I recommend keeping track of those results and de-duplicating locally, as that would likely be faster and less error-prone in this scenario.
Alternatively, you can just allow CreateFolderV2Async (assuming that's what you're using) to run whenever you are getting 'not_found', and catch the CreateFolderError on that. I.e., to ignore it if it contains a WriteConflictError.Folder.
Anyway, a RetryException isn't actually explicit rate limiting. (That would be RateLimitException.) That just indicates an issue on the Dropbox servers so you can have your app retry the request if you wish.

I think that's the best solution. Thanks for the suggestion!
In the meantime, working on implementing that, I'm now hitting the ratelimit exceptions, so can you please let me know what the allowed rate is so that I can pace my code appropriately? Thanks.
