What causes this error: Failed to upload file. Error:[object Object]

Trying to upload a file to a folder on Hololens emulator via Device Portal File Explorer, including to locations I have uploaded to successfully before. Restarting the device did not help.

    Hello there,

    I know this is an old Topic but I have the same Problem right now. upgrading the Emulator and using Edge instead of (in my case) Chrome doen't seem to solve the problem for me.

    Thanks in advance for every answer.
