SQL Server: Add data source failed `sql server exception`

Hi - I was trying out Hasura 2.0 on SQL Server and keep on getting below exception
```
Add data source failed
sql server exception
```
_Details_ button is not really providing any details other than:
```
[
{
"definition": "localtestdb",
"reason": "sql server exception",
"type": "source"
}
]
```
I'm using both Hasura and [SQL Server](https://docs.microsoft.com/en-us/sql/linux/quickstart-install-connect-docker?view=sql-server-ver15&pivots=cs1-bash) locally with Docker. And, followed the instructions from [Hasura Docs](https://hasura.io/docs/latest/graphql/core/databases/ms-sql-server/index.html#database-ms-sql-server)

**Database URL**
`Driver={ODBC Driver 17 for SQL Server};Server=localhost,1433;Database=testDB;Uid=SA;Pwd="YoStPw0rd";`

**Image Tags**
- hasura/graphql-engine `v2.0.0-alpha.6`
- postgres `12`
- mcr.microsoft.com/mssql/server `2019-latest`

I also tried to check the Hasura container logs and couldnt find anything useful.
Is there a way to understand more information about the `sql server exception` it is complaining about?
Or if someone else faced the same issue, please share the steps to resolve it..
