using throw from within then($onRejected)

[quazardous]

I'm trying to handle errors with $reactBrowser->requestStreaming($method, $url, $headers, $body)->then()

$reactBrowser->requestStreaming($method, $url, $headers, $body)->then(
    function (ResponseInterface $response) {},
    function (\Exception $reason) {
            echo "DEAD !!!\n";
            throw $reason; // <<< It's trapped somewhere
   });
$loop->run();

I'm throwing the $reason but it's trapped somewhere.

Is it a bug or is it by design ?

Hey @quazardous, this is not a bug and a known behavior, you can read more about it in reactphp/promise#87. You can try to handle the exception by using try catch, but we're aware that this is not the best behavior. As we speak we're in the middle of preparing a new major version (v3), where we also want to introduce better error and exception handling, @clue wrote about this in our wish list ticket here on GitHub : https://github.com/orgs/reactphp/discussions/472#discussioncomment-3880271

I hope this helps 👍
