我正在拆分 YAML 文件，但是在生成代碼時出現以下異常：java.lang.NullPointerException at io.swagger.v3.parser.ResolverCache.updateLocalRefs(ResolverCache.java:162) at io.swagger.v3.parser.ResolverCache.loadRef(ResolverCache.java:152) at io.swagger.v3.parser.processors.ExternalRefProcessor.processRefToExternalResponse(ExternalRefProcessor.java:205) at io.swagger.v3.parser.processors.ResponseProcessor.processReferenceResponse(ResponseProcessor.java:76) at io.swagger.v3.parser.processors.ResponseProcessor.processResponse(ResponseProcessor.java:38) at io.swagger.v3.parser.processors.OperationProcessor.processOperation(OperationProcessor.java:56) at io.swagger.v3.parser.processors.PathsProcessor.processPaths(PathsProcessor.java:83) at io.swagger.v3.parser.OpenAPIResolver.resolve(OpenAPIResolver.java:49) at io.swagger.v3.parser.OpenAPIV3Parser.readLocation(OpenAPIV3Parser.java:53) at io.swagger.parser.OpenAPIParser.readLocation(OpenAPIParser.java:19)我正在努力實現的示例（openapi.yaml）：openapi: 3.0.0info: title: Common Data Types version: "1.0"paths: /{appId}/subscriptions: get: summary: read all of the active subscriptions for the app responses: '200': description: OK (Successful) content: application/json: schema: type: array items: $ref: '#/components/schemas/subscription' '400': $ref: './common.yam#/components/responses/E400' '401': $ref: './common.yam#/components/responses/E401'components: schemas: subscription: type: string和common.yaml：openapi: 3.0.0info: title: Common Data Types version: "1.0"paths: {}components: responses: E400: description: Bad request E401: description: Unauthorized語境：$ tree├── common.yaml└── openapi.yaml$ openapi-generator version3.3.0

此問題已在openapi-generator-cli-4.0.0-beta3.
但是，對于3.3.0以下版本將起作用
我觀察到的是導致問題的if common.yaml文件被修改為common_modified.yaml，問題得到解決并且沒有Null指針異常。
YAML 導致問題common.yaml
openapi: 3.0.0
info:
title: Common Data Types
version: "1.0"
paths: {}
components:
responses:
E400:
description: Bad request
E401:
description: Unauthorized
修改后的 YAML 修復了問題common_modified.YAML
openapi: 3.0.0
info:
title: Common Data Types
version: "1.0"
paths: {}
components:
responses:
E400:
description: Bad request
content:
applictaion/json:
E401:
description: Unauthorized
content:
applictaion/json:
如果從外部引用，似乎開放 API 會查找內容。不過不確定。但對我有用！
