错误 - 虽然模式中包含突变，但未为突变配置模式

Question

Although i have created a mutation and inserted it in graphql schema, it returns the error, Checked with other instances of same error there isn't any solution regarding the current issue

'schemas' => [
        'default' => [
            'query' => [
                'articles' => App\GraphQL\Query\ArticlesQuery::class,
            ],
            'mutation' => [
                'updatearticle' => App\GraphQL\Mutation\UpdateArticle::class
            ],
            'middleware' => [],
            'method' => ['get', 'post'],
        ],
    ],
