I just tried to reproduce with the steps you describe, but this seems to
work correctly.
You mention changing the query in a table input transform triggers the
error, but your screenshot shows the metadata perspective, and the stacktraces
in the `localhost.2023-04-03.log` file you added point to (a keystroke event
in) the explorer perspective.
The error is there, we'll just need to work out a clear reproduction path.
Can you please provide some more details on how/when you get this error?
