Server sometimes throws "Http: connection closed before message completed"

[eibens]

Error:

error: Uncaught (in promise) Http: connection closed before message completed

Here is some discussion: denoland/deno#11595

The aforementioned discussion mentions that one must correctly await promises. Testing with using await event.respondWith seems promising.

Still occurs. At lesat now with a better stacktrace. It often seems to happen when the server is freshly started and the tab opened from the link in edcb's output.

error: Uncaught (in promise) Http: connection closed before message completed
          await event.respondWith(response);
