Opening a CRM module in the Make editor shows a mapped lookup empty, and saving wipes it

Contact ID renders empty with its Map toggle off

This trap has not been confirmed recently and may be out of date.

Verified 2026-07-18 · Confirmed by 0 builders · Trust 50/100

Cause

Some app modules, including the Bigin by Zoho update modules, do not render a mapped lookup value in the editor. Saving the module writes the empty field back.

Fix

Do not edit these modules in the editor. Fetch the blueprint, change the mapper in code, and write it back through the API.

Apply

GET /api/v2/scenarios/{id}/blueprint, edit flow[n].mapper, PATCH /api/v2/scenarios/{id} with {"blueprint": "<json string>"}, then POST /api/v2/scenarios/{id}/start

Affects: Make Bigin by Zoho app (v2 modules), July 2026
