NullReferenceException using a stored procedure with a UUID input parameter

[elandev]

Describe the bug

Getting a NullReferenceException with a stored procedure inserting into UUID column data type. I get the following NullReferenceException:

The stored procedure works, when I remove the UUID parameter from the stored procedure.

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.

The project is set up to run both tests with and without the UUID parameter. SQL insert statement works. Stored procedure works without UUID, but get the NullReferenceException when using the stored procedure with the UUID parameter.

Expected behavior

Expected the stored procedure insert with the UUID to work.

• Dotnet version: 6.0
• Database: 10.11.2-MariaDB
• Library version: Insight 6.3.11
