worker columnization failed; columnizing on the main thread

Warnings reference › source.stream.columnize

Identifier: source.stream.columnize
Raised by: The grid (core)
Since: 1.16.0

What happened

The worker was asked to columnise a chunk and failed, so the chunk was columnised on the main thread and the worker path is ruled out for the rest of this stream. No rows are lost. A superseded request during a reload is normal and is not reported.

The fix

The error is attached to the console line.
