NullReferenceException calling InsertAsync

[elandev]

Describe the bug

Get a NullReferenceExceptionwhen calling InsertAsync with a stored procedure. See exception below.

When I use ExecuteAsyncwith the same stored procedure it works.

Object reference not set to an instance of an object.

Steps to reproduce

1. Load the attached project with Visual Studio 2022.
2. Set up MariaDB as the database (10.11.2-MariaDB).
3. Edit the server, database name and credentials for the connection string.
4. Restore Nuget packages and build the solution.
5. Run the project.

Expected behavior

I expected the InsertAsyncto work and return the auto-incremented ID.
