A customer is getting “Can’t upload” when they try to upload something. I can duplicate the problem, but I don’t have enough information to tell them why. How do I figure this out?
In order to find out the reason for the error, you need to check the response from upload API. See this topic for details
Hope that helps. If this doesn’t help, let us know.
In this case, I think it was a file size error (bigger than our plan allows.)
The problem is that isn’t what’s communicated to the user. They get a generic error message. Is there away to know that the file is too big on the client side and explain why they are having an issue?
