Can you show the complete code?

it looks like the email is missing or it could be that you create username only as your login credentials instead of using email.

Hey @arashsaffari ,

In Shield, all users are required to have a unique email address, which is mandatory during the registration process. However, it's possible to log in using other identifiers besides email, such as a username, employee ID, etc.

Considering this, it seems that the user you're trying to change the password for does not have an email address associated with their account.

Please verify that the user has an email by running the following command:

php spark db:table auth_identities

Ensure that the user has a valid email (field secret).

If the user does have an email and the problem persists, please provide the minimal code necessary to reproduce the error.

I have an email address stored in the database. The problem is that when using $user->email, the getEmail() function in the User entity is not being called. However, when I call the $user->getEmail() function in the controller, $user->email is populated with the email address. Interestingly, when I work with $user->password_hash, the getPasswordHash() function in the entity is called, and I receive the hash. It's worth noting that I have the email stored in my auth_identities table, and my login credentials use instead of the email.

Can you show the code how you call the user data? if you call it correctly then the email displays well.

For example:

$usersModel = auth()->getProvider();
//find user where id is "7"
$user = $usersModel->find(7);
//show user email
dd($user->email); // result "example@pointerpointer.com"

It appears that you have written incorrect code regarding User.

I can reproduce a similar error.

in my case, I added a personal field to $personalFields where the type of the field or its value is an integer. To prevent this error, we should cast the personal field value to a string.

I can reproduce the error in this issue.

It seems you added a personal field to $personalFields where the type of the field or its value is an integer. To prevent this error, we should cast the personal field value to a string.

In my case, it’s specifically related to $personalFields, so this situation is different.
