I am using the version |
I have the same error, only when calling SingleOrDefaultAsync(). And when I'm using the non-async version, SingleOrDefault, I'm only getting a warning and lots of selects:
On EF Core 2.1, MS SQL 2017 |
I see that the warning and the error are caused by Mapster. When I'm using AutoMapper, it all works correctly. |
Clearing milestone to discuss propose-close in regular triage. |
@Mortana89 - Can you share a repro project? |
No sorry, it's been too long, we've switched to Cosmonaut somewhere in March and are using that in production now, so will be too difficult for me to repro now... |
Just finished upgrading all our Cosmos provider queries to the Async equivalent, and am getting the following exception on a very simple query:
var result = await _context.ExecutionParts.Include(x => x.ExecutionRun).SingleOrDefaultAsync(x => x.Id == executionPartId);
return result;
