Hi everyone. I am using SuperToken with nestjs, I am trying out the api override feature to customise the signup flow. I have the auth module from the docs, I created auth.service inside the module. Inside the auth.service, I created a method called signUp and a private method isEmailSupported, then I inject the auth.service into supertokens.service and set the signUp function to the value of the signUpPOST key. When I trigger the signup, I got an error from nestjs, saying that "this.isEmailSupported is not a function". Is it a supertoken specific problem or nestjs problem?
hey @andrew1123 this is a JS releated error
i mean neither supertokens, nor nestjs
But I got no build time error from typeScript
You should make the isEmailSupported an arrow function
and same goes for signUp
Oh, thanks, I'll try
I worked! But why? I seldom see arrow function declaration in typescript class

@rp Thank you! Understood the concept, also found an alternative way to solve it. Changed the signUpPOST value to
Copy code
Yea. that works too!
But people generally prefer to use arrow functions since it's prettier.
