sanctum多角色认证的问题

在项目中存在商户和客户两种身份，使用sanctum做的api认证，

但是问题是Merchant model生成的token不能通过auth:merchant中间件的验证，反而是Customer model生成的token可以通过auth:merchant中间件的验证。请问这块是否有对应的配置能让token和对应的验证项对应起来。

配置和代码如下：

config/auth.php

'guards' => [
    'customer' => [
    'driver' => 'sanctum',
    'provider' => 'customers'
    ],

    'merchant' => [
    'driver' => 'sanctum',
    'provider' => 'merchants'
    ]
],

'providers' => [
    'customers' => [
    'driver' => 'eloquent',
    'model' => App\Models\Customer::class,
    ],

    'merchants' => [
    'driver' => 'eloquent',
    'model' => App\Models\Merchant::class
    ]
],

Model

use Laravel\Sanctum\HasApiTokens;
use Illuminate\Foundation\Auth\User as Authenticatable;

class Merchant extends Authenticatable
{
    use HasFactory, SoftDeletes, HasApiTokens;
}

use Laravel\Sanctum\HasApiTokens;
use Illuminate\Foundation\Auth\User as Authenticatable;

class Customer extends Authenticatable
{
    use HasFactory, SoftDeletes, HasApiTokens;
}

merchant.route.php

Route::post('login', [LoginController::class, 'login']);
Route::middleware(['auth:merchant'])->group(function (){
    Route::get('test', [ProductController::class, 'test']);
});

customer.route.php

Route::post('login', [LoginController::class, 'login']);
Route::middleware(['auth:customer'])->group(function (){
     Route::get('test1', [ProductController::class, 'test1']);
});

MerchantController

public function login(Request $request)
{
    $merchant = Merchant::query()->find(1);
    $token = $merchant->createToken($merchant->name);
    return $this->ok([
    'token' => $token->plainTextToken
    ]);
}

CustomerController

public function login(Request $request)
{
    $customer = Customer::query()->find(1);
    $token = $customer->createToken($merchant->name);
    return $this->ok([
    'token' => $token->plainTextToken
    ]);
}
