Regex filter for geocontext layers do not work in some instances

[NyakudyaA]

Problem

When we populating the geocontext service the regex is not working consistently especially for WFS layers.

When the regex is defined as gml:name it consistently work provided the data has a column with name.

If the data has a column gml:category the service does not work.

In some instances the regex has to be kartoza:category.

Solution

We need to identify and get the service working consistently especially when populating the json.
When do we use kartoza:column_name vs gml_column_name vs gml:name
