Swagger codegen to Java Spring generates incorrect file response entity from OpenAPI component of binary format

In the end, I switched from

<plugin>
  <groupId>io.swagger.codegen.v3</groupId>
  <artifactId>swagger-codegen-maven-plugin</artifactId>
  <version>3.0.14</version>
  ...
</plugin>

to

<plugin>
  <groupId>org.openapitools</groupId>
  <artifactId>openapi-generator-maven-plugin</artifactId>
  <version>4.2.3</version>
  ...
</plugin>

This plugin got it right and generates Resource instead of ResponseEntity
