Hi
*Issue:*
When a file is uploaded via FileManager it gets storage directory path from
STORAGE_DIR config variable. but in case of pgAdmin4 Runtime it is set to
None, that means STORAGE_DIR path should be the root directory.
The path formed to file was "None/filename.ext'. but it should be
'/filename.txt' which is now fixed.
Please find attached patch and review.
Thanks,
Surinder Kumar
