Monitoring

We have deployed a fix for anyone experiencing the following error when using OAuth with Snowflake:

"error":"Unable to process OAuth callback! error=RPError: iss mismatch, expected snowflake, got: https://example.snowflakecomputing.com/oauth","errorDetail":""

This change introduces case sensitivity for the configured Snowflake URL. If you continue to receive the above error and have a mixed-case URL, a workaround is to change the URL to all lowercase.
