Weekly SF_ReplicateAll failing

There are a host of errors, mostly “Error occurred creating primary key for table.” in tables AppDefinition, AuraDefinitionBundleInfo, AuraDefinitionInfo, FormulaFunction, FormulaFunctionAllowedType, FormulaFunctionAllowedType and other.

but also “Using FullCopy because the FieldChangeSnapshot table does not exist.”

threw a SOAP error: Error System.Web.Services.Protocols.SoapException: EXTERNAL_OBJECT_UNSUPPORTED_EXCEPTION: Enter a valid ParentID.    at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)   at DBAmpAZ.sforce.SforceService.query(String queryString)    at afo220l.Uh.w()

Should I wipe out all the tables and start again? Please advise.

Regards

Andre
