Hi bspindia,

😁 Your file comes uploaded correct, seems. If this file is image, as you're stating, missing proper file extension in the file name can disturb the file handling/previewing on Dropbox site (in spite it's still valid). 🤷 Unfortunately, Dropbox isn't so smart. That's why don't forget set proper file extension whenever possible! 😉 Otherwise don't rely on proper Dropbox processing (including preview) more than just storage.

bspindia As Здравко mentioned, you need to set the file extension (and name) when uploading to Dropbox via the API.

For example, when uploading using the /2/files/upload endpoint, you should set the full path, including file name and extension, of where you want to upload the file in the "path" parameter.

In the output you shared, the resulting path is "/undefinedundefined", so it appears you have not properly set the path, name, and extension for the file when uploading it. (It looks like you attempted to set the path to two undefined values that you joined.) You'll need to fix your code to set that properly.
