SonarLint only shows this popup when it catches a certain exception from the underlying analyzer. So I would strongly advise that you:
- set
sonarlint.output.showAnalyzerLogs
andsonarlint.output.showVerboseLogs
totrue
in your user settings - reload the window / restart VSCode
- open a TS file, wait for the popup to appear
- go to the SonarLint Output (on Windows: Ctrl+Shift+P, “SonarLint: Show SonarLint Output”)
- copy the contents of the output pane and paste it here enclosed within a
```
block
Interestingly enough, I remember another old thread where a similar symptom was reported (with some issues reported despite the annoying error popup).
