### Expected Behavior

Given that I have no buckets yet, I was expecting to see some kind of empty list (maybe in a fancy tui frame) with an exit status of 0.

### Actual Behavior

The above stack trace, with an exit status of 1.

### Steps to Reproduce

At the moment, all I have to do is run `linode-cli obj ls` to reproduce it, but I don't know what state it is contingent on (e.g. would it stop erroring out if I create a bucket? is there a linode api deployment that adds/removes a this request checksum thing? etc).

Start at linodecli/plugins/obj/__init__.py, especially _get_boto_client, and trace its call from list_objects_or_buckets in plugins/obj/list.py. Reproduce `linode-cli obj ls` and inspect the botocore Config options involved in the traceback. Done means the command handles an empty bucket list without a TypeError and exits successfully.
