Declaring a nullable variable in a razor page produces error-CodePudding

I am getting the following error:

CS1061 'Task' does not contain a definition for 'data' and no accessible extension method 'data' accepting a first argument of type 'Task' could be found (are you missing a using directive or an assembly reference?)

This is the line that errors out

  _OldRecord = await GetPossibleDuplicateRecord(Convert.ToInt64(OldId)).data;

I believe I am getting this error because _OldRecord is null at this time. I tried to add the ? when I am declaring the variable like this:

private PossibleDuplicateRecord? _OldRecord = new PossibleDuplicateRecord();

and I still get the error. A co-worker told me to put the .data at the end of the await and both of these threw the same error. This is in the code-behind of a razor page if that is any help. I am out of ideas

Also, I have the proper using reference "using System.Threading.Tasks" so I know that the using directive is there

Priority problem?

await GetPossibleDuplicateRecord(Convert.ToInt64(OldId)).data;

The way i read it, you await the .data, not the task.

(await GetPossibleDuplicateRecord(Convert.ToInt64(OldId))).data

would be the data.
