From : Transform File from c:/
To Transform File from
I hope it could help

Alright, I think I figured it out. It seems there's definitely a bug in PowerBi when it tries to auto-convert to the new metadata format. The issue is indeed with special characters in the Transform File functions. To fix this issue, I did the following:
This was a total pain to do once, let alone the 20 more times i'll have to do it in various reports, but for me, this resolved the issue and I can now refresh my data from within PBI Desktop.
Same problem here as well. From my error message is seems there are characters in the file path that PowerBi isn't handling well. Worked before the enhanced metadata upgrade just fine though.
I have exactly the same problem......
