Description

Our OpenAPI spec contains a servers block at the bottom, similar to this:

  "servers": [
    {
      "url": "/some-path"
    }
  ]

This path would then be used in ClientUtils.CONTEXT_PATH as a path prefix for all endpoints.
But because of the changes in this PR #20896 this no longer works ( @devhl-labs ).

Our auto-generated NuGet packages now no longer work because this path is missing.

Is the servers block of the OpenAPI spec no longer supported? Is there a better/new way to set a prefix path for all endpoints? Or is this simply a bug?

[devhl-labs]

Not sure I understand the issue. The CONTEXT_PATH is still in use here

In my use case, I also have a servers block, albeit a fully qualified url, but it works for me.

Which produces the correct url

Can you explain how your case is different? If you can send a PR with the fix, please do.
