crm field mapping error after salesforce schema change
Fixes field-mapping errors after a Salesforce schema change: renamed fields, changed types, or deleted fields break sync mappings. Re-run describe, update the mapping, and backfill. Use when syncs fail after a Salesforce change. Not for initial mapping setup.
TL;DR
Someone renamed a field, changed its type, or deleted it in Salesforce, and the sync mapping still points at the old shape. Pull a fresh describe, diff it against the mapping, update the changed entries, and re-run the failed sync window. Mappings rot; describe is the source of truth.
Error
Sync error: mapped field Account.Industry__c not found on object.Steps
- Run describe on the object and compare field names and types to the sync mapping. Expected: you find the renamed, retyped, or deleted fields.
- Update the mapping: point at the new API name, adjust for type changes, or remove deleted fields. Expected: the mapping matches reality.
- Check whether data written during the breakage went to the wrong place or nowhere. Expected: you scope the damage window.
- Backfill the broken window after fixing the mapping. Expected: no gaps in the synced data.
- Subscribe to schema change notifications or diff describe on a schedule in the agent. Expected: the next change is caught before the sync breaks.
When to use
- Syncs fail after a Salesforce admin change.
- An agent's writes start failing with field errors after months of success.
- After managed package upgrades.
When not to use
- First-time mapping setup (different task).
- HubSpot-side schema changes (different describe).
Tool compatibility
- Salesforce describe API; any sync tool with field mappings.
- Schema diffing in agent code.
Variant phrasings
mapped field not found
Renamed or deleted; re-describe and remap.
sync broke after Salesforce release
Same pattern from the timing side.
Why it happens
Mappings are snapshots of a schema at setup time. Salesforce schemas evolve, and nothing invalidates the snapshot automatically, so the mapping silently rots.
Edge cases
- Type changes (text to picklist) break writes even when the name is unchanged.
- Renamed labels do not affect mappings, but renamed API names do; check the API name.
- Deleted fields in the recycle bin still describe; the mapping may look fine while writes fail.
