Summary
When a YAML/XML-configured operation declares an
openapi.parametersentry without aname(orin),YamlResourceExtractor::buildOpenapi()accessed$parameter['name']/$parameter['in']unguarded. This emitted aWarning: Undefined array key "name"(the original symptom of #8013, surfaced viaapi:openapi:export) followed by a crypticTypeErrorfrom theParameterconstructor.nameandinare required fields of an OpenAPI parameter object. The extractor now throws a clearInvalidArgumentExceptionnaming the missing required key, instead of leaking a PHP warning and producing broken output.The original report used the removed 2.6
collectionOperations/openapi_contextsyntax (that array path is gone fromOpenApiFactory), but the modern config equivalent (openapi.parametersarrays) reaches the same unguarded code in the extractor.Reproduction
Declaring an operation
openapi.parametersentry with nonamekey crashed withUndefined array key "name"+TypeErrorrather than a helpful error.Test plan
testOpenApiParameterWithoutNameThrowsClearException(fails before fix, passes after).YamlExtractorTestpasses; php-cs-fixer + PHPStan clean.Fixes #8013
