I have a project with JDG materialization. I have set
After load script to: execute BookCacheSource.native('swap cache names');
and
Before load script to: execute BookCacheSource.native('truncate cache');

When I generated Dynamic VDB and I want to deploy it, server shows me error that:

org.teiid.api.exception.query.QueryParserException: TEIID31100 Parsing error: Encountered ", \"teiid_rel:MATVIEW_AFTER_LOAD_SCRIPT\" 'execute BookCacheSource.native('[*]swap[*] cache names" at line 10, column 188.
Was expecting: "," | ")"

When I added another apostrophe to procedures in the DDL,
execute BookCacheSource.native(''truncate cache'');
execute BookCacheSource.native(''swap cache names'');
deploy was successful.
I think that DDL parser should add it automatically.
