  _headers => HTTP::Headers {
    content-length => 4561,
    content-type => text/html;charset=UTF-8,

DBG>$res->content

As you can see HTTP::Response object has 4561 bytes of content, but ->content returns nothing. Also _content is empty

Ouch! The response body is filled in asynchronously, so maybe you can circumvent the issue by waiting some time (1s should be well enough) as a workaround.

The real fix is to return a proxy object that blocks when the ->content (or ->decoded_content or whatever) methods are called to wait for the fetched content.
