Fetch: connection closed before message completed

[retog]

My application executes many fetch requests. Even if all await fetch calls are in try/catch blocks execution terminates with the message:

error: Uncaught (in promise) TypeError: error sending request for url (http://fuseki:3330/ds/update): connection closed before message completed
    at async mainFetch (deno:ext/fetch/26_fetch.js:266:14)
Process exited with code 1

The same message seems to appear also when serving HTTP:

deno/cli/tests/unit/http_test.ts

Line 153 in 5c06368

// TODO(ry) If we don't call httpConn.nextRequest() here we get "error sending

, #11595

I've tried adding delays between fetches as well as setting keepalive to false. Any idea on how to avoid this error?

Update

Turns out I did miss catching the rejections of a promise. Catching the exception prevents the program from terminating.
