Description

I don't know which component in the stack is wrong.

- springdoc-openapi-starter-webmvc-ui will serve up swagger-ui/index.html, locally 100% and when deployed to a AWS API Gateway (HTTP-style) only some .js files and the .html file serve, the rest blowing up in the API Gateway response with no error message

I think the minimal repro is to add `springdoc-openapi-starter-webmvc-ui ` (via pom.xml) to the ping controller example (which is a bad name for an endpoint because it clashes with the automatically provided route of AWS API Gateway, I usually have to rename it to pong)

I told the container to treat application/javascript and text/css as binary and API Gateway stopped trying to do something (unnecessary encoding/decoding) to the response and now swagger-ui loads.

I'm leaving this here because other issues have run into the same problem and came up with worse workarounds (like stop even trying to serve some content types on API Gateway at all)

That this works locally in tomcat makes me think that something is wrong with API Gateway or serverless-container.

```xml

org.springdoc
springdoc-openapi-starter-webmvc-ui
2.8.6

```

```java
public class StreamLambdaHandler implements RequestStreamHandler, Resource {
private static SpringBootLambdaContainerHandler handler;
static {
try {
handler = SpringBootLambdaContainerHandler.getAwsProxyHandler(Application.class);
LambdaContainerHandler.getContainerConfig().addBinaryContentTypes("application/javascript");
LambdaContainerHandler.getContainerConfig().addBinaryContentTypes("text/css");
} catch (ContainerInitializationException e) {
// if we fail here. We re-throw the exception to force another cold start
e.printStackTrace();
throw new RuntimeException("Could not initialize Spring Boot application", e);
}
}
}
```

Research direction

Start with the linked StreamLambdaHandler.java example and inspect the serverless container's binary content configuration for AWS responses. Reproduce the issue with springdoc-openapi-starter-webmvc-ui, then determine whether application/javascript and text/css should be recognized by default; done means the Swagger UI assets load through API Gateway with coverage for the expected response behavior.
