hmm, maybe that should follow curl's logic:

https://curl.se/docs/manpage.html#-f

key part: By default, curl does not consider HTTP response codes to indicate failure.

That's fair, should I add -f/--fail option then?

actually, --fail-with-body may be closer to what awscurl is doing...

Sounds good -- please update pr

done, tested locally

$ python3 -m awscurl --service lambda https://<my-function>.lambda-url.ap-southeast-2.on.aws/ 
{"data":"Hello from Lambda!"}
$ echo $?
0

$ python3 -m awscurl --fail-with-body --service lambda https://<my-function>.lambda-url.ap-southeast-2.on.aws/ 
{"data":"Hello from Lambda!"}
$ echo $?
22
