Your worker called response.clone()

Your worker called response.clone(), but did not read the body of both clones. This is wasteful, as it forces the system to buffer the entire response body in memory, rather than streaming it through. This may cause your worker to be unexpectedly terminated for going over the memory limit. If you only meant to copy the response headers and metadata (e.g. in order to be able to modify them), use new Response(response.body, response) instead.
