Failed publish troubleshooting

Open the Publishing Queue to see the error for each item. Most failures are missing required fields or category, an expired connection, or a marketplace rejection.

Try this first

1. Open Sync status and find the failed run. Each run shows its result and log.
2. Open Marketplace Health and check the channel's connection state and last confirmed read.
3. If the connection shows as expired, reconnect it from Connections.
4. Retry the job once. If it fails again with the same message, contact support with the job reference shown on the run.
