Retool Email Internal Server Error

I am getting an error when trying to use the Retool Email resource. Under the output menu of the resource the error message is just "Internal Server Error". I was triggering this resource from a query with additional scope so I thought that was the issue but if I remove all of my additional scope variables from the email query I still get the same error. Then I tried a new email resource with text entered for each field and I get the same error. There is no error in the console either. Have I run into a bug or is there something I am doing wrong?

Thanks for flagging this! This was a bad feature flag rollout that we've since reverted. Let me know if you still run into this.
