在 Lighthouse 5 中，报错：Failed to find class Modules\\ThemeStore\\Validators\\ThemeAsset\\CreateThemeAssetInputValidator in namespaces [App\\GraphQL\\Validators] for directive @validator.

1、在 Lighthouse 5 中，报错：Failed to find class Modules\\ThemeStore\\Validators\\ThemeAsset\\CreateThemeAssetInputValidator in namespaces [App\\GraphQL\\Validators] for directive @validator.。如图1

PS E:\wwwroot\object> php artisan lighthouse:ide-helper
Wrote schema directive definitions to E:\wwwroot\object/schema-directives.graphql.

   Nuwave\Lighthouse\Exceptions\DefinitionException  : Failed to find class Modules\ThemeStore\Validators\ThemeAsset\CreateThemeAssetInputValidator in namespaces [App\GraphQL\Validators] for directive @validator.

2、确认类 Modules\\ThemeStore\\Validators\\ThemeAsset\\CreateThemeAssetInputValidator 已经迁移至 Modules\\ThemeStoreGraphQl\\Validators\\ThemeAsset\\CreateThemeAssetInputValidator 。如图2

3、在指令 @validator 中的类文件路径调整为：Modules\\ThemeStoreGraphQl\\Validators\\ThemeAsset\\CreateThemeAssetInputValidator 后，不再报错。

input ThemeAssetCreateInput @validator(class: "Modules\\ThemeStore\\Validators\\ThemeAsset\\CreateThemeAssetInputValidator") {
    "主题ID"
    themeId: String!,
    "内容"
    content: String!,
    "路径，相对于主题的路径，如 pages/index.blade.php"
    key: String!,
}
