Error with Git plugin: Git: Right-hand side of 'instanceof' is not an object

[flzara]

Since a couple of days, I have this error message each time I want to stage, unstage, commit, … in the source control view of the latest version of Theia IDE : Git: Right-hand side of 'instanceof' is not an object

I have no errors or warning in the git log output
I'm running Theia IDE version 1.61.0 as an AppImage on an up-to-date Ubuntu 24.04 LTS with 2 external extensions: AsciiDoc and Run on Save.

Thank you.

@flzara Thank you for reporting this issue!
@rschnekenbu Can you reproduce this issue? I'm wondering if this is a regression in the VS Code compatibility. Thank you in advance!

[flzara]

@planger yw. Do you want me to open a formal issue?

[rschnekenbu]

@flzara I will check on my side and we can open an issue depending on what I find. Thanks for asking!

@flzara I tried to run the same test case in roughly the same environment, ubuntu 22.04, appimage Theia IDE 1.61.0 and I installed the 2 mentioned extension. In my gif example, please note that gitlens extension is disabled.

I cannot get the message you mention, and git commit, git stage actions and so on are working fine.
Can you check in the console of the developer tools (help => toggle developer tools => console) if you have anymore details about that issue?
