a spread join skipped the field "{fieldName}...

What happened

A spread attribute resolved to a field name the parent row already carries as one of its own (base) fields. The spread field is skipped - the base value stands - so a custom field can never silently overwrite a real column. Warned once per field name, not per parent.

The fix

Rename the base field, or change the spread's prefix/name so the attribute lands on a field the parent does not already carry.

The smallest fix

join: { from: 'companyAttr', foreignKey: 'companyId', spread: { name: 'attribute', value: 'value', prefix: 'cf_' } }
