Trouble handling 500 Internal Server Error Response

Issue

In our project, it seems like if the .fetch call receives a status 404, 401 etc. it goes to the .catch as expected.

Meanwhile, if the .fetch call's response is a 500 Internal Server Error, it does not move on at all. It neither goes the the .then bracket, nor the .catch. See code snippet for illustration

const configOptions: ReactNativeBlobUtilConfig =
            Platform.OS === 'ios'
                ? {
                      fileCache: true,
                      appendExt: '.pdf',
                      path: <path>
                  }
                : //android
                  {
                      addAndroidDownloads: {
                          useDownloadManager: true,
                          notification: true,
                          mime: 'application/pdf',
                      },
                  };

ReactNativeBlobUtil.config(configOptions)
            .fetch(
                'GET',
                `url....`,
                {
                    headers...
                }
            )
            .then((res) => {
                console.log('This does not happen when 500 response');
            })
            .catch((e) => {
                console.log('this does not happen when 500 response');
            });

We tried multiple setups, but could never get it to work. The only way to handle it that we found was to simply cancel the request after a set time.

        // Cancel request after 3 minutes in case of internal server error
        setTimeout(() => {
            task.cancel();
        }, 1000 * 60 * 3);

Edit:
After further testing, this seems to be the case specifically for running on android, as iOS seems to be handling the response as expected.

Same case for me! Is the timeout the only solution to this? I don't like that approach tbh. It just hangs infinetly, no log on javascript side or something like that

Info:
react-native: 0.73.9

Tested on Android 10 to 14.
