WordPress incorret password for username or email, added using “wp_insert_user”

So i have created my own user, using below code. I am more than certain that i have a correct password when i login. But for some reason that I dont know i always have “The password you entered for the email address/username is incorrect”. Can someone shed some light on me!!!

 function insert_into_wp_users(){
    // Check for nonce security      
    if (!wp_verify_nonce( $_POST['nonce'], 'active-aupair-nonce-string' ) ) {
        die();
    }
    $user_id = wp_insert_user( array(
       'user_email'   => $_POST['email'],
       'user_password'=> $_POST['password'],
    //    'first_name'   => $_POST['firstName'],
    //    'last_name'    => $_POST['lastName'],
       'user_login'   => $_POST['userLogin'],
       'role'         => 'subscriber'
     ));
     if( is_wp_error( $user_id  ) ) {
        wp_send_json_error($user_id->get_error_message());
    } else {
        wp_send_json_success($user_id);
    }
    die();
}

P.S I confirm that my user exist. WordPress just cant validate the password.

EDIT

You’re using user_password instead of user_pass.

I lost an hour using your parameters.

Additionally, it seems that you should also be able to use wp_create_user() as you’re not doing anything fancy.

wp_create_user()

Creates a new user with just the username, password, and email. For more complex user creation use wp_insert_user() to specify more information.

add_action( 'init', 'wpso66859906' );
if ( ! function_exists( 'wpso66859906' ) ) {
    function wpso66859906() {

        $user = 'thomas';
        $email = '[e-mail]';
        $password = 'password';

        if ( ! username_exists( sanitize_user( $user ) ) && is_email( sanitize_email( $email ) ) && ! email_exists( sanitize_email( $email ) ) ) {
            
            wp_create_user( sanitize_user( $user ), trim( $password ), sanitize_email( $email ) );
            
        };
    };
};
