When IAM role is not set it tries to connect without key and secreat and therefore throws \Aws\Exception\CredentialsException exception:
https://github.com/catalyst/moodle-fileconverter_librelambda/blob/master/classes/converter.php#L202-L206
Therefore the setting page is not displayed at all:
See objectfs as an example:
https://github.com/catalyst/moodle-tool_objectfs/blob/master/classes/local/store/s3/client.php#L215-L234
Also as part of IAM role change this line was changed:
c68fe43#diff-b9a34794852807cf1a15b1525ad6e3dbR106
Thus, proxy is used even when the setting is set to 0.
And the last one:
This return isn't expected. Should be bool
