Hi, I'm using tap-jira to extract data from Jira API

select:
        - issues.*

schema:
          issues:
          fields__customfield_10140:
              type: [string, 'null']
            fields__customfield_10141:
              type: [string, 'null']
            fields__customfield_10142:
              type: [string, 'null']
            fields__customfield_10151:
              type: [string, 'null']

I've added these schemas on these custom fields but these 3 specific are coming with only null values. I also have other custom fields on the schema, but they are 'Select List (multiple choice)', and I can get the values. The problem is when the fields are 'Select List (single choice)' Picture with the 2 fields types Does anyone got into this issue before? Any hints on what I can do here? Thank you in advance
