Steps to Repro

Like you. Same error in 7.5.0 version and previous. With Spring Boot 3.2.4 and use option spring boot 3.x in maven plugin.

My spec is:

openapi: "3.1.0" info: version: 1.0.0 title: ApiRest paths: /files/retrieve: post: summary: Retrieve a file operationId: retrieveFile tags: - File requestBody: required: true content: application/octet-stream: schema: type: string format: binary responses: '201': description: OK
