snowflake sso connection using sqlalchemy does not work - snowflake-cloud-data-platform

Question

i am trying to configure an sso connection in my python script.
here's my code:
import sqlalchemy
def get_snowflake_engine(warehouse="ETL", environment=None):
username = ‘userx#domainx.com'
account = ‘accountx
database = ‘dbx’
authenticator = 'externalbrowser'
return sqlalchemy.create_engine(
f"snowflake://{username}:#{account}/{database}?authenticator={authenticator}&warehouse={warehouse}"
)
engine = get_snowflake_engine(environment='production')
connection = engine.connect()
try:
result = connection.execute('SELECT NOW()').fetchall()
print(result)
finally:
connection.close()
engine.dispose()
i expect my browser to pop with an authorisation form (we use google for sso)
and i get a messeage on the terminal, but nothing happens on the browser:
Initiating login request with your identity provider. A browser window should have opened for you to complete the login. If you can't see it, check existing browser windows, or your OS settings. Press CTRL+C to abort and try again...
after a while i get an exception
any advice?
using MacOS, Pycharm
BTW i configured on DataGrip a connection using authenticator = 'externalbrowser' and it works as expected.
TIA

I had a similar problem, the connector logs showed that it was missing the AWS region in the connection URL (eu-west-1 in my case) so I fixed by adding:
...
region = 'eu-west-1'
...
return sqlalchemy.create_engine(
f"snowflake://{username}:#{account}.{region}/{database}?authenticator={authenticator}&warehouse={warehouse}"
)
This resulted in the browser authentication window opening in browser and the query returning successfully.
