Hi @Brun0oO

This is a bug with our latest release. We will work on releasing a fix soon.

georgii.borovinskikh · August 7, 2024, 11:31am

@Brun0oO Hi. We’ve released a fix for this, version 8.2.1.

I have installed version 8.2.1.96841 and am still seeing this exact error message

georgii.borovinskikh · August 20, 2024, 7:32am

Hi @bdekker
I tried to reproduce the issue and I can confirm that I can no longer reproduce it with 8.2.1, but can consistently reproduce it with 8.2.0.
Could you verify the extension version in Extensions > SonarLint > Help > About SonarLint?
Also, another thing is to check if you have telemetry.xml file in <user folder>\AppData\Roaming\SonarLint for Visual Studio

I did confirm I have a telemetry.xml file in the location specified.

georgii.borovinskikh · August 20, 2024, 12:39pm

Thank you for providing the logs. This seems like a different issue than what was fixed in 8.2.1.

Could you please send me the contents of the <user folder>\AppData\Roaming\SonarLint for Visual Studio\Bindings folder? It seems to be that there is some binding data there that is corrupted.

There are no personal secrets stored in that folder, but if you would like to share it privately, I have sent you a DM you can reply to.

Sorry for the inconvenience!

georgii.borovinskikh · August 21, 2024, 2:16pm

Hi @bdekker

I tried to reproduce the problem with the binding files you’ve sent me and, unfortunately, I can’t.

If this issue appears for you consistently, I would suggest deleting the <user folder>\AppData\Roaming\SonarLint for Visual Studio folder and trying again. This will remove the 2 project bindings you have, so you will have to re-do it. A good shortcut to do it would be to export your bindings and then, after you delete the folder, to import them again

bdekker · August 21, 2024, 8:18pm

Deleting the entire folder seemed to have solved it, thanks!
