ImportError: cannot import name '_rfc_1738_quote' from 'sqlalchemy.engine.url'-CodePudding

I am using a python snowflake connector from the following package: snowflake-sqlalchemy

from sqlalchemy import create_engine
engine = create_engine(...)

It used to be working but it's now failing with this weird error.

I tried to switch to older version of the package, but can't get rid of this error.

Here is the fulll stack trace:

Looks like this is a known issue will get resolved in v1.4.3, per the release notes:
