Airflow 2.1.0: Snowflake connection not enabling snowflake "role"

Apache Airflow version: 2.1.0

Kubernetes version (if you are using kubernetes) (use kubectl version):

Environment:

• Cloud provider or hardware configuration: AWS EKS, AWS ECS
• OS (e.g. from /etc/os-release): Debian GNU/Linux 10
• Kernel (e.g. uname -a):
• Install tools:
• Others:

What happened: When creating a snowflake connector using a snowflake hook(using UI), not able to add snowflake roles in the extras. here is the screenshot of the connection which I am creating

but once I am done saving it I lose the role and if I edit my connection this is what I see in the UI

so Extra gets populated with all the other placeholders. I can see that https://github.com/apache/airflow/blob/4b14d93f25f237b8cca17f57352c253f292a111b/airflow/providers/snowflake/hooks/snowflake.py#L89 you guys are returning some value to the widget but it is not having a snowflake “role” definition.

https://github.com/apache/airflow/blob/4b14d93f25f237b8cca17f57352c253f292a111b/airflow/providers/snowflake/hooks/snowflake.py#L105

I also updated the JSON object and created it as a nested JSON {{"role": "test"}} following the placeholder from the above function but still, the behaviour remains the same.

What you expected to happen:

"placeholders": {
                'extra': json.dumps(
                    {
                        "role": "snowflake role",
                        "authenticator": "snowflake oauth",
                        "private_key_file": "private key",
                        "session_parameters": "session parameters",
                    },
                    indent=1,
                ),
                'host': 'snowflake hostname',
                'schema': 'snowflake schema',
                'login': 'snowflake username',
                'password': 'snowflake password',
                'extra__snowflake__account': 'snowflake account name',
                'extra__snowflake__warehouse': 'snowflake warehouse name',
                'extra__snowflake__database': 'snowflake db name',
                'extra__snowflake__region': 'snowflake hosted region',
                'extra__snowflake__aws_access_key_id': 'aws access key id (S3ToSnowflakeOperator)',
                'extra__snowflake__aws_secret_access_key': 'aws secret access key (S3ToSnowflakeOperator)',
            }

If I follow above code I should be able to pass the snowflake role into the Extras. But this behaiour is missing

How to reproduce it:

Create a connection with connection type snowflake in airflow UI.

Anything else we need to know:

Issue is closed, but wanted to note that the same issue is happening when trying to add a private key file (using “private_key_file” parameter) in the Extra field. I am using Apache Airflow 2.1.0. Should I file a new bug report?
