I propose to do set -eu at the beginning and adjusting ${FILE} in line 50 which is unbound. Finally it should read »an UPLOAD« to be correct.

Does not work for me: with --utc I get AWS authentication requires a valid Date or x-amz-date header and without it The request signature we calculated does not match the signature you provided
