How do I see the data that a linter is receiving?

I'm trying to setup a new project and I'm getting this when using `@typescript-esline/parser`:

```
"[typescriptreact] diagnostic handle fail: [eslint] Unexpected token E in JSON at position 0"
```

How do I see the content that eslint is seeing? I can't figure out what "E" is.

Thanks!

The issue names @typescript-eslint/parser and reports a JSON parsing error while using the diagnostic language server. No file, test, or entry point is identified; first clarify whether the expected outcome is documentation or a debugging/logging change, then define how success will be verified.
