Hi,
I'm trying to get Dataflow Gen2 to refresh through our On Prem gateay.
Gateway is 3000.198.9
Had issues before and I think all ports are open that need to be.
I've also tried with various on prem sources (SQL and csv) and get the same message.
Error Message:
Error Code: 999999, Error Details: Couldn't refresh the entity because of an issue with the mashup document MashupException.Error: The value is not updatable. Details: Reason = Expression.Error;Detail = #table({"Name", "Id", "Data", "Schema", "ItemKind", "ItemName", "IsLeaf"}, {});Microsoft.Data.Mashup.Error.Context = System GatewayObjectId: 2bcf3e12-740c-47e3-86f3-b94626567200 (Request ID: c754e592-b9ec-4b7c-ae20-a8dcbe2d9b1b).
Any ideas?
