[Bug]: Custom base path is wrongly handled in Diff View

[cjunekim]

Describe the bug

If you use custom base path, Open diff view doesn't work. It seems to search under a wrong place : custombase\custombase

Relevant errors (if available)

Suppose there is Document under custombase and it's a folder and a custom base.

This is the error you get when the custom base path is customebase, for example:

Uncaught TypeError: Cannot read properties of null (reading 'path')
