WordPress: User with custom role cannot access wp-admin

Question

First of all I am a WordPress learner. So sorry if my code looks stupid!

I have created a custom theme with a custom user role. I am not developing any plugin.

In my fucntions.php file I have written the following code to create a User role. Users assigned to this role are supposed to login to the admin but only be able to access their Profile pages.

add_action('init', 'yrc_cst_register_role_customer_service_rep');

/**
 * Register new user role
 */

function yrc_cst_register_role_customer_service_rep() {

    $wp_roles = new WP_Roles();

    $wp_roles->remove_role('subscriber');
    $wp_roles->remove_role('editor');
    $wp_roles->remove_role('contributor');
    $wp_roles->remove_role('author');

    $service_rep_caps = array(
        'read'              => false,
        'create_posts'      => false,
        'edit_posts'        => false,
        'edit_others_posts' => false,
        'publish_posts'     => false,
        'manage_categories' => false,
        'manage_options'    => false,
    );

    add_role('customer_service', __('Customer Service'), $service_rep_caps);
}

I have removed all roles except Administrator, because no other role is required for this portal. Administrator will only create Users with Customer Service role.

I have no third party plugin installed in the system.

Users with the custom role are able to login to the system through a custom login page which is working OK. But whenever they are trying to access their Profile page the following error message comes up:

Sorry, you are not allowed to access this page.

Is there anything like 'edit_profile' => true?

I must be doing something wrong but my limited knowledge is not enough to figure this out. Any suggestion would be highly appreciated.

You might be able to do it like this :

This should clone the subscriber role capabilities and create your role for it.

add_action('init', 'CreatecloneRoleSubscriber');

function CreatecloneRoleSubscriber()
{
    global $wp_roles;
    if ( ! isset( $wp_roles ) )
        $wp_roles = new WP_Roles();

    $sub = $wp_roles->get_role('Subscriber');
    //Adding a 'new_role' with all subscriber caps
    $wp_roles->add_role('customer_service', 'Customer Service', $sub->capabilities);
}

EDIT : Read discussion in question comments

Just change the manage_options to true in your case But note that by allowing manage_options to true, those user will have access to other parts of dashboard as well

 $service_rep_caps = array(
    'read'              => false,
    'create_posts'      => false,
    'edit_posts'        => false,
    'edit_others_posts' => false,
    'publish_posts'     => false,
    'manage_categories' => false,
    'manage_options'    => true, // Most plugins and pages check for manage_options for checking access level to allow access to pages and settings.
);

Just found this solution which i consider really clean to enter wp-admin with a new role:

Add access cap to backend

Add the cap view_admin_dashboard & read to your new role.

Show the admin bar

Add this function to your wordpress.

# functions.php

add_filter( 'show_admin_bar', function () {

    if ( current_user_can( 'view_admin_dashboard' ) )
        return true;
    
    return false;

}, 10);
