one text

I tried following steps for install passport authentication for my api's. but i get everytime {"error":"Unauthenticated."} while fetching simple data.

1. composer require laravel/passport

2. php artisan migrate

3. app/model > users.php file change

   use Laravel\Passport\HasApiTokens; use HasApiTokens, Notifiable, SoftDeletes, HasRoles, HasFactory;

4. config > auth.php My Guards be like

   'api' => [
       'driver' => 'passport',
       'provider' => 'users',
   ],
   

5. providers > AuthServiceProvider.php

   if (! $this->app->routesAreCached()) {
       Passport::routes();
   }
   

Note :

• i tried almost all relatable solutions on stackoverflow as well laracast. Still not able to find the solution.
• I've Laravel 7 earlier and i upgraded to Laravel 8. and i also checked for updating dependencies
• My Login url http://127.0.0.1:8000/api/login works perfectly and returning a bearer token successfully
• i've also passed Accept : application/json & Authorization : Bearer <MY_BEARER_TOKEN> in postman request
