Regarding supertokens-web-js `supertokensEmailPassword.signUp` , is the returned promise rejected in case of FIELD_ERROR? 
Initially I wrote the code inside .catch to deal with FIELD_ERROR but on debugging found that the code does not reach `.catch`, but it is inside `.then`. 
Is it intended?

the promise is not rejected in that case.

the promise will be rejected only in cases of a >= 400 error status code

What will be the result object schema in that case?

The references mentions this

```
Promise<{ fetchResponse: Response; status: "OK"; user: UserType } | { fetchResponse: Response; formFields: { error: string; id: string }[]; status: "FIELD_ERROR" }>
``` 
Which means 
resolved - `{ fetchResponse: Response; status: "OK"; user: UserType }`
rejected - `{ error: string; id: string }[]; status: "FIELD_ERROR" }`

but it seems the rejected schema is also appearing in resolved state. is rejected schema same?

> he promise will be rejected only in cases of a >= 400 error status code
what about this?

im not sure how i can make this more clear. Please see the swagger API spec 🙂

you can just show a somethign went wrong message on reject. On resolve, you check the status from the body and change the UI accordingly.
