Flank: NullPointerException on windows while fetching artifacts

[jakob-grabner]

I get a NullPointerException while fetching artifacts after the test run completed. I guess it is a Windows issue since it works just fine on linux.

Yeah, that looks like a Windows bug. I'll look into it.

[ynsok]

The same, any idea how to solve it ?

[pawelpasterz]

Hey @ynsok @jakob-grabner
Recently we introduced new way of creating results (based on TL api, not fetched xml) Could you verified if this approach solved your issue? Please, use snapshot version https://github.com/Flank/flank/releases/tag/flank_snapshot
Let me know

[bootstraponline]

I think the way to test this issue would be to run flank in a windows VM.

[Sloox]

I have a physical windows device will look into this problem

[Sloox]

Due to current work on supporting windows. This error has not been observed on both Windows with and without WSL2.
The original error message contained a NPE based on pathing.
Windows Pathing fixes were applied here:

This ticket will remain open until the larger ticket is closed.

[bootstraponline]

I'm closing the ticket since I think this issue is fixed. If you see the issue again, please let us know!
