Format of ODBC connect not matching exactly what my script is asking

Question

my code dbconnect command:

mysql-odbc://sct-mssql-db.c6p0dl1fqnlk.us-east-1.rds.amazonaws.com:1433/sct_mssql_db?mssql_user&schemaconversion

But Script actually want:

expected: db='dbtype[-odbc]://hostname[:port][/dbname[?user[&Pass]]]'

And I am getting error :

{"wrong_db_string": "Wrong format for dbconnect. Given: %s, expected: db='dbtype[-odbc]://hostname[:port][/dbname[?user[&Pass]]]'"

What is wrong with my above dbconnect command that it is not matching with expected result.
