business-messaging-api_v23.0.yaml is not valid

[WernerRaath]

The OpenAPI spec seems to not be fully valid. When we try and validate the Swagger Doc using the following command, we see it returning business-messaging-api_v23.0.yaml: attribute components.parameterGroups is unexpected

docker run --rm node:26-alpine sh -c "apk add wget && npm i -g swagger-spec-validator && wget https://raw.githubusercontent.com/facebook/openapi/main/business-messaging-api_v23.0.yaml && swagger-spec-validator business-messaging-api_v23.0.yaml"

When we try and to a TS codegen from it, it also fails

docker run --rm node:26-alpine sh -c "apk add --no-cache openjdk17-jdk && npm install -g openapi-typescript @openapitools/openapi-generator-cli && npx @openapitools/openapi-generator-cli generate -i https://raw.githubusercontent.com/facebook/openapi/main/business-messaging-api_v23.0.yaml -g typescript-axios -o /tmp/"

returns

Exception in thread "main" org.openapitools.codegen.SpecValidationException: There were issues with the specification. The option can be disabled via validateSpec (Maven/Gradle) or --skip-validate-spec (CLI).
