The integration instance completes without error and nothing arrives at the other end.
Most likely causes
- The target accepted the message and rejected it later. An asynchronous endpoint acknowledges receipt, not processing, so success here means delivered rather than accepted.
- A mapping produced an empty payload. Sending nothing successfully is still success.
- A filter or condition skipped every record. A routing rule that matches nothing completes cleanly.
- It went to the wrong environment. Connection endpoints are per environment and are the easiest thing to carry over from a test.
What to check
- The actual request payload sent, not the mapping preview — an empty element is visible there and nowhere else.
- Whether the target has its own error queue or rejection log, and what is in it.
- The endpoint URL the connection resolved to at runtime.
- Whether the instance count matches the number of source records you expected.
