flux-lsp-browser: RuntimeError: Out of bounds memory access (evaluating 't(r)')

## About the bug

At some point, my queries with built in variables stop completing with error
```
error @5:33-5:34: record is missing label env

error @2:19-2:20: record is missing label timeRangeStart

error @2:43-2:44: record is missing label timeRangeStop
```

If i remove all variables, the query will run.

The console error is:

```
