Error in version 07.20.3237 on DB.DBA.R2RML_MAKE_QM_FROM_G?

Virtuoso Universal Server RDF Data Management

Hello!

With the new version of Openlink Virtuoso (Version: 07.20.3237, Build: Jun 7 2023 (f3d88f16b)), when I execute the following command from ISQL:

EXEC ('SPARQL ' || DB.DBA.R2RML_MAKE_QM_FROM_G ('urn:geca:tables:r2rml:mappings1'));

I receive the following error message:

SQLState: 22023
Message: SR008: Function id_to_iri needs a string or UNAME or IRI_ID or NULL as argument 1, not an arg of type rdf (246)

With only the returned error message, I can’t even determine if there is any error in the R2RML, since if I execute it only, I don’t encounter any errors, and the error only occurs when I execute the R2RML_MAKE_QM_FROM_G command.

This is the entire SPARQL/R2RML script, where you can find the Triple mappings too:

However, when using the previous version (Version: 07.20.3236, Build: Feb 27 2023 (795af34a7)) with the same code, I do not receive error message.

It seems that there has been a change in the new version that causes this error.
Is there a way to understand what is causing the error? This would help find a solution and correct it.

What is the DDL for the SQL tables being used as when I attempt to run your script it fails with the error:

-- Line 735: EXEC ('SPARQL ' || DB.DBA.R2RML_MAKE_QM_FROM_G ('urn:geca:tables:r2rml:mappings1'))

Does our sample Generating Virtuoso RDF Quad Map Storage patterns from R2RML scripts example which calls R2RML_MAKE_QM_FROM_G work for you as it works for me with the latest docker Version 07.20.3237-pthreads for Linux as of Jun 7 2023 (f3d88f16b) container ?
