To resolve this issue, you should verify the context type in your mapping. Ensure it’s either ‘category’ or ‘geo’. If it’s a custom type, make sure it’s properly defined and supported. Also, check for any spelling or syntax errors in your mapping.

 }
 MappingParser.checkNoRemainingFields(name; contextConfig);
 return contextMapping;
 }
