title: How to debug TypeScript NS_BINDING_ABORTED for POST-Requests
body: <p>I got a simple functionality that calls my backend, via POST-Request. It uses the same wrapper function that is used everywhere in the project, just does &quot;fetch&quot; and is called in some async/await-manner.</p>
  <p>body is just static stuff, some ID and two dates. pretty straightforward - the wrapper-function would fail if body weren't supplied at all or similar.</p>
  <p>but the request &quot;always&quot; (well, there were one or two successfull tries in about 100 retries) fails with NS_BINDING_ABORTED</p>

  <p>Google tells me that message means I had some cache hit and the request was canceled - but cache is disabled, Header-Vars should prevent it AND adding random stuff to the URL doesn't do shit. (sometimes that OPTIONS-call gets through, but POST itself fails still)</p>
  <p>nearly all post-requests in that project are done with this exact same wrapper.</p>
  <p>Anyone got some ideas where I could look to debug this?</p>
