+**Problem**: Getting `Error: 260000: account is empty` error with non-empty `account` configuration after upgrading to v1, with the same provider configuration which worked up to v0.100.0
+
+**Solution**: `account` configuration [has been removed in v1.0.0](https://github.com/Snowflake-Labs/terraform-provider-snowflake/blob/main/MIGRATION_GUIDE.md#removed-deprecated-objects). Please specify your organization name and account name separately as mentioned in the [migration guide](https://github.com/Snowflake-Labs/terraform-provider-snowflake/blob/main/MIGRATION_GUIDE.md#removed-deprecated-objects):
+* `account_name` (`accountname` if you're sourcing it from `config` TOML)
+* `organization_name` (`organizationname` if you're sourcing it from `config` TOML)
