The account parameter was omitted from the snowflake.connector.connect() call. The account value is an empty string or None (e.g., read from an env var that is not set). Using a legacy connection method that no longer auto-discovers the account. Misconfigured secrets manager or configuration file missing the account key. Typo in the parameter name (e.g., account_name instead of account)

Add the account parameter: snowflake.connector.connect(account='myaccount', ...).. The account value should be the account identifier only (e.g., xy12345.eu-west-1), not the full URL.. Check that the environment variable or config file supplying the account value is populated: echo $SNOWFLAKE_ACCOUNT.. If using a connection profile (connections.toml), ensure the account field is present and non-empty.. Verify you are not passing account_name — the correct parameter name is account.

Power BI Refresh Error:
251001

What does this error mean?

The Python connector was called without specifying a Snowflake account name. The account parameter is required for every connection and identifies the Snowflake account to connect to.

Common causes

1The account parameter was omitted from the snowflake.connector.connect() call
2The account value is an empty string or None (e.g., read from an env var that is not set)
3Using a legacy connection method that no longer auto-discovers the account
4Misconfigured secrets manager or configuration file missing the account key
5Typo in the parameter name (e.g., account_name instead of account)

How to fix it

1Add the account parameter: snowflake.connector.connect(account='myaccount', ...).
2The account value should be the account identifier only (e.g., xy12345.eu-west-1), not the full URL.
3Check that the environment variable or config file supplying the account value is populated: echo $SNOWFLAKE_ACCOUNT.
4If using a connection profile (connections.toml), ensure the account field is present and non-empty.
5Verify you are not passing account_name — the correct parameter name is account.

Frequently asked questions

What is the correct format for the account parameter?

Use the account identifier without the .snowflakecomputing.com suffix: e.g., xy12345 for US East, or xy12345.eu-west-1 for other regions. Find it in Admin > Accounts in the Snowflake UI.

Can I use the full URL as the account parameter?

No — pass only the account identifier. The connector appends .snowflakecomputing.com automatically.
