I am using MySQL and .NetCore. I have a table with Json data type. However, I am having trouble registering here via c #. I'm getting an error. How can I save Json data without destroying it?

DB Tablo
Id => type Int
Name => type nvarchar
JsonData => Type Json

I am saving Json data through database. But it gives an error with C # code.

What I have tried:

sqlconn = new MySqlConnection( ConnectionString );
      if (sqlconn.State != ConnectionState.Open)
      cmd = new MySqlCommand("call Ynkys.sp_JSON_INSERT(2, 22, 'Test', '"+jsonString+"')", sqlconn);
      cmd.CommandType = CommandType.StoredProcedure;

{"You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Test', '{\"Id\":\"22\",\"Name\":\"AAAAAAAAAA\"}')'' at line 1"}

I don't think "call" works in this context. You need a (SP) name and parameters.
