How to set custom timeout duration?

Describe the issue

I am hitting a timeout error when performing a put request. I would like to tweak the timeout duration to be much more than 20 seconds.

Steps to Reproduce

1. Make a put request last more than 20 seconds.

Current behavior

The app crashes

Thank you for investigating @aajtodd , I am pretty sure the json file we upload is much lighter than 500MB (maybe 25MB at most would be my guess) that being said it is in a highly concurrent environment therefore it might be that the request is not given high priority since we have a lot of coroutines running on the Dispatchers.IO.

I will continue to investigate to seek a better understanding but it’s good that at least you’re able to reproduce, we’ll be waiting for a fix in the meantime.

Thanks a lot

I’ve been able to reproduce this with a very large upload (1GB). The 20 sec timeout is coming from the retry middleware which is erroneously applying timeouts to the whole request (including upload time).

I’m a little surprised the size document you are dealing with is causing this though. I couldn’t reproduce this under 500MB but that could also of course just be differences in upload speed or possibly if you have a highly concurrent environment the request is getting starved.
