trouble in data sync

ChenShiyang

hi everyone

we just have a trouble in data sync.

we have created some record types from the database, but one of them failed in data sync.

the status is "failed" in sync history.

the detail shows "Alert: Unable to sync due to a system failure. Issue identifier: [e0bcc3cb-4961-443e-be9d-ced7237ae97c]".

is there some proboble reasons for this trouble?

Thank you all.

    Do you see any additional information in the stdout log during that time? Often there will be a more detailed error message in those logs. In addition, can you share some more information about this such as:

    • What is the source type (database, web service, salesforce)
    • What kind of sync is it (manual sync, scheduled sync, sync from write to data store entity)
    • Is this the first time it failed or has it failed consistently

    It is database.

    Record Type Save and Manual Sync and Scheduled sync are all failed. But other records created from other database have been synced successfully.

    We can see the data at data preview which is in the database, but there`s no data in the list.

    Ok I think I'd still be interested in understanding what's in the stdout log - usually that log can tell you more information about what has occurred. If you haven't used that log before, you can access it by selecting the navigation menu at the top and selecting "System Logs" (assuming you're on cloud) and finding the log called `tomcat-stdout.log.<date of issue>`.

    Thanks for your reply.

    There's part of the log. And the full ver is upload as an attachment.

    it seems there's a uncoverable error but I don't understand what it is......

    Ok nothing seems obvious to me, and I haven't see that "Failed to parse request contents error" before. I'd recommend opening a support ticket with Appian to see if they can help you investigate.
