如何更改TokenObtainPairView的错误响应消息？

from rest_framework_simplejwt.serializers import TokenObtainPairSerializer

class CustomTokenObtainPairSerializer(TokenObtainPairSerializer):
    def validate(self, attrs):
        data = super().validate(attrs)
        # 自定义错误消息
        if 'non_field_errors' in data:
            data['error'] = '自定义错误消息'
        return data

from rest_framework_simplejwt.views import TokenObtainPairView

class CustomTokenObtainPairView(TokenObtainPairView):
    serializer_class = CustomTokenObtainPairSerializer

from django.urls import path
from .views import CustomTokenObtainPairView

urlpatterns = [
    path('api/token/', CustomTokenObtainPairView.as_view(), name='token_obtain_pair'),
    # 其他URL配置...
]
