ColumnListParameter fails with IndexError: list index out of range

[galaxyproject-sentryintegration]

Not sure of the logic here. The problem is that there are more numerical columns for this metadata type than columns in the file.

The best explanation is that the datatype was wrong?

[wm75]

This could happen with tabular datasets with a first line with fewer columns than subsequent lines.
In that case, the datatype will detect as many columns as there are on the longest line, which then causes this error when indexing into the first line.
