We’ve added “field” and “field_message” to the Batch Subscribe error response. You’ll see data in these fields when a merge field error is encountered.

Previously, when you encountered a merge field error during a Batch Subscribe operation, you didn’t see any details about the field in the error. This can cause headaches when you’re troubleshooting a remedy.

These additional fields, when present, should provide more insight into how to resolve an issue.
