Browser extension import not working

[Tobi0]

JabRef version

5.6 (latest release)

Operating system

Windows

Details on version and operating system

Windows 10 20H2 19042.1706

Checked with the latest development build

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

This seems to occur on Windows only if pwsh.exe is not installed, but powershell.exe installed.

Issue

The Jabref Browser Extension (Firefox) shows "Error while sending to JabRef" and no reaction from the client at all (either opened or not).

Possible Cause

This change on buildres/windows/JabRefHost.bat: JabRef/jabref#8432
There is probably an issue with the errorlevel check.
If I change the file back to only the @powershell.exe command, it works.

The transfer from JabRef/JabRef to JabRef/JabRef-Browser-Extension created new labels "type bug" and "os:windows", which i can't get rid off. Sorry :/

Thanks for the investigation @Tobi0! I think you are right, the second %errorlevel% does not reflect the outcome of the second test. In fact, a similar question has been raised here https://stackoverflow.com/questions/50348437/wrong-value-of-errorlevel-in-nested-if-in-bat-file. Could you please try the workaround/fix posted there, and if it indeed works open a PR at the jabref repo? That would be awesome!
