Describe the bug you're encountering

Semantic error at paths./test.delete.requestBody
DELETE operations cannot have a requestBody.

This is inaccurate, for OpenAPI 3.1.0:

In other cases where the HTTP spec is vague (such as GET, HEAD and DELETE), requestBody is permitted but does not have well-defined semantics and SHOULD be avoided if possible.

I also tried setting:

openapi: 3.1.0

But that did not work.

If this not a bug, and just a case of the 3.1.0 spec not being yet supported, apologies for creating this ticket.

To reproduce...

Steps to reproduce the behavior:

1. Go to https://editor.swagger.io/
2. Paste the above YAML

Expected behavior

No error message.

Additional context or thoughts

Cloned and update issue details from #1929 .

Your example is openapi: 3.0.0 not 3.1. In 3.0.x, DELETE and GET cannot have requestBody.

OAS 3.1 is not supported yet, this is tracked in #2638.

That makes sense, apologies for this.
