Dual-write initial sync fails - "Server returned non-success HTTP response"

Hi,

We're getting a fairly generic error message when instigating Dual-write initial syncs on a number of maps:

Executed leg:From Dynamics 365 for Finance and Operations Customer groups to Dynamics 365 for Sales msdyn_customergroups - GB1
 with exported records count: 0, ImportRecordsErrorCount: 0, ImportRecordsInsertedCount: 0 and ImportRecordsUpdatedCount: 0 
ErrorsDetails:
Type=Microsoft.Dynamics.Integrator.Exceptions.IntegratorClientException, Msg=Type=Microsoft.Dynamics.Integrator.Exceptions.IntegratorClientException, Msg=FinOps export encountered an error.(Type=Microsoft.PowerApps.CoreFramework.Communication.Http.NonSuccessHttpResponseException, StatusCode=BadRequest, Msg=Server returned non-success HTTP response). ExportErrors: (1)
Record Id: , ErrorMessage: Type=Microsoft.Dynamics.Integrator.Exceptions.IntegratorClientException, Msg=Type=Microsoft.Dynamics.Integrator.Exceptions.IntegratorClientException, Msg=FinOps export encountered an error.(Type=Microsoft.PowerApps.CoreFramework.Communication.Http.NonSuccessHttpResponseException, StatusCode=BadRequest, Msg=Server returned non-success HTTP response). ImportErrors (0)

We've started with all legal entities enabled, and DMF shows that an export package is being created for DAT (with no records), then every single other legal entity fails with the above message and does not create the export package. Execution history for the job doesn't show any errors recorded.

All health checks in Dual-write pass.
These are standard OOB Dual-write maps.
The entity data in Finance can be read using OData calls in a browser
Live sync seems to work fine if the map is just started without an initial sync.
This is a Tier 2 environment running version 10.0.44.
No errors logged against the app registrations.
Have tried resetting the link, truncate and refresh entities.

Can anyone suggest further troubleshooting steps please? It's logged with Microsoft, but they're taking their time to respond since it's a non production environment.

Thanks in advance.

@Anthony Blake Not yet, I'm afraid. I will make sure to update here if/when we get a resolution. In the interim we've had to recreate the environment on 10.0.43. Luckily not a production environment yet!

Hi @Phil Matthews @PD-17062034-0

I'm experiencing the same issue this evening, have either of you had any response from MS or found a workaround?

Thanks,

Anthony

Dual-write initial sync fails - "Server returned non-success HTTP response"

All solutions are up to date.

Just to add extra information to this, we have now narrowed down the scope of the problem.

During the initial sync from FO to CE, an export package is only created for the first legal entity which is attempted to be synced and all others fail with the non success HTTP response. The Legal Entities are synced in the order that they are shown in the Legal Entities tab within Dual-write.

For example if DAT, LE1, LE2, and LE3 are the legal entities in order, an export package for DAT will be created and creation of packages for LE1-3 will all fail. If we then delete the DAT legal entity from the config, save, and re-add it, it is then added to the end of the list (and so is synced last). If we then repeat the initial sync under these conditions, LE1 will succeed, LE2, LE3, and DAT will fail.

This is almost certainly, as stated below, a bug with Dual-write in 10.0.44.

Have you also checked the FO related solutions on Dataverse to see if there are update avail? If yes, update them and retry.

We have exactly the same problem for TST12 and UAT environments running on version 10.0.44.

It worked last week and suddenly stopped after 10.0.44 update, so the only answer is Microsoft ticket.

I just reported it, so I should know something more in 2-3 working days.
