Description

I have at least one user in my tenant where email verified is true as a string

{
    "email_verified": "true",
}

When I use the SDK to load the user, it fails to unmarshal, returning the error json: cannot unmarshal string into Go struct field .embed.email_verified of type bool

Expectation

The SDK should successfully load the response without throwing an error and with parsing the string value as a boolean

The v1 version of the SDK had this code to support the issue.

// UnmarshalJSON is a custom deserializer for the User type.
//
// We have to use a custom one due to possible inconsistencies in value types.
func (u *User) UnmarshalJSON(b []byte) error {
	type user User
	type userAlias struct {
		*user
		RawEmailVerified interface{} `json:"email_verified,omitempty"`
	}

	alias := &userAlias{(*user)(u), nil}

	err := json.Unmarshal(b, alias)
	if err != nil {
		return err
	}

	if alias.RawEmailVerified != nil {
		var emailVerified bool
		switch rawEmailVerified := alias.RawEmailVerified.(type) {
		case bool:
			emailVerified = rawEmailVerified
		case string:
			emailVerified, err = strconv.ParseBool(rawEmailVerified)
			if err != nil {
				return err
			}
		default:
			panic(reflect.TypeOf(rawEmailVerified))
		}
		alias.EmailVerified = &emailVerified
	}

	return nil
}

Reproduction

1. Have a user where the email_verified value is a string
2. Load the user through the SDK
3. Observe error json: cannot unmarshal string into Go struct field .embed.email_verified of type bool

Auth0 Go SDK version

2.9.0

We are also affected by this bug. Looks similar to #691

The v1 code had this fix f3a34cb as mentioned

Hey @nikolaik @weirdian2k3,

Sorry for the delayed response. I think I missed providing an update here.

We're currently looking into a fix for this issue and will share an update as soon as we have more information.
