SPARQL Regex using the modifier "i" crashes using AWS Redshift as data source

[Ste fan]

Hello :)

I recently opened a bug ticket: https://github.com/ontop/ontop/issues/738

But maybe I'm doing things super wrong.
The issue is since I'm using the "i" modifier in my regex command e.g.

"FILTER (regex(str(?value), "1234", "i"))"

I'm getting the Error:

"ERROR in i.u.i.o.a.c.impl.QuestStatement - com.amazon.redshift.util.RedshiftException: ERROR: Invalid preceding regular expression prior to repetition operator. The error occurred while parsing the regular expression: '(?>>>HERE>>>i)1234'."

It works fine without the "i" flag.

Does anyone has an idea how I could avoid the error without changing the SPARQL query?

Regards Stefan
