Thanks @User, I missed the backend config. But follow-up question, I am not seeing the

handleCustomFormFieldsPostSignUp

function being executed. Here is my code on the backend. I was expecting to see that console.log in my server terminal. Am I doing something wrong?

recipeList: [
            ThirdPartyEmailPasswordNode.init({
                signUpFeature: {
                    formFields: [
                        {
                            id: "userSlug"
                        }
                    ],
                    handleCustomFormFieldsPostSignUp: async (user, formFields) => {
                        let { id, email } = user;
                        console.log(">>> successful sign up", id, email, formFields);
                    }
                }
            }),
            SessionNode.init()
        ]
