Hello,
Yesterday we had a a few scheduled refresh failures, but today almost all of our datasources are are failing to refresh. All of these have to do with Business Central Web Services datasources. Here is an example of the error given: Expression.Error: The OData connector failed with the following error: We cannot convert the value null to type Record... . The exception was raised by the IDbCommand interface. Table: Division.
Using the desktop app I can refresh the datasources perfectly fine, but the PBI Service fails. I have gone through and reselected the datasource in the naviagtion step and then republished the to the workspace to test. After this the datasource refreshed without error, but upon the next scheduled refresh the datasource failed again with the same error. This leads me to believe that there is an issue with the PBI Service or Business Central, but as the Desktop app refreshes correctly it seems more likely that it is the PBI Service. Anyone else having similar issues?
