It is useful to know where in the process your recipe failed.

• Transform Phase: Failures here are usually related to your recipe logic (e.g., a bad REGEXREPLACE) or data parsing (e.g., a JSONEXTRACT formula on an invalid JSON string, ref: 1.83). These errors happen before Sliced Bread tries to save anything to Salesforce.
• Load Phase: Failures here are almost always Salesforce-specific errors (validation rules, triggers, “Record Locked” errors, etc.). The “Status Reason” field will contain the error from Salesforce.
