Phone number not passed to Google Sheets despite being mapped and present in JSON

Hi everyone,
I’m facing a strange issue in my scenario and would appreciate any help.

Context:

  • I’m parsing a JSON from a WhatsApp form using the Parse JSON module.
  • The parsed value screen_0_Telefono_mvil_4 (user’s phone number) appears correctly in the JSON output (e.g. 666444777).
  • I’ve mapped this value to a field in Google Sheets (Individual_Customer_Information_Phone) in the Add row module.

The problem:

  • Despite the field being mapped and visible in the mapping editor (Raw: screen_0_Telefono_mvil_4), the value does not appear in the final INPUT of the Google Sheets module, and is not written to the spreadsheet.
  • Other values from the same JSON (name, email, birthdate, etc.) work perfectly.
  • I’ve tried:
    • Renaming the column
    • Mapping to a different field
    • Using a different sheet
    • Creating an alias with Set variable
    • Removing potential conflicts (e.g. no duplicated mappings)

Extra details:

  • Value exists in the bundle and is not empty.
  • There are no errors in the scenario.
  • Google Sheets receives all other mapped values except this one.
  • Tried with different numbers and inputs — same result.

Questions:

  • Has anyone experienced Make ignoring a single field in a bundle like this?
  • Could it be related to Make’s internal parsing or filtering mechanism?

Thanks a lot in advance!

A
