Example Code

import os
from dotenv import load_dotenv
from langchain_community.utilities import SQLDatabase
load_dotenv()

def get_snowflake_uri() -> str:
    env = os.environ.copy()
    return "snowflake://{}:{}@{}/{}/{}?warehouse={}&role={}".format(
        env["USERNAME"],
        env["PASSWORD"],
        env["ACCOUNT"],
        env["DATABASE"],
        env["SCHEMA"],
        env["WAREHOUSE"],
        env["ROLE"],
    )
print(get_snowflake_uri()) # snowflake://my_actual_username:my_actual_password@my_actual_account/my_actual_database/my_actual_schema?warehouse=my_actual_warehouse&role=my_actual_role
db = SQLDatabase.from_uri(get_snowflake_uri())

Description

This exact code ran a week ago, but now this error. I'm able to connect with the snowflake using Snowflake-connector like this but it ran fine.

import snowflake.connector
conn = snowflake.connector.connect(
    account = '<my-account>',
    user = '<my-username>',
    password = 'my-password',
    database = 'my-database',
    schema = 'my-schema',
    warehouse = 'my-warehouse',
    role='my-role')

pd.read_sql('SELECT 1;', conn)
>>>

I also tried with different versions of SQLAlchemy and snowflake-sqlalchemy too but no luck. The same error is encountering with LlamaIndex too. Any suggestion would be helpful.

My current package versions are:

System Info

snowflake-connector-python==3.12.2
snowflake-sqlalchemy==1.6.1
SQLAlchemy==2.0.36
