This repository uses the Blue style guide, which puts closing parentheses on the following line in cases like this

Suggested change
digest(MD_MD5, request.content))
digest(MD_MD5, request.content)
)

Supposedly automatic formatting suggestions are set up but that appears to not have occurred here.

You can write this a bit more concisely like so:

content_hash = bytes2hex(digest(MD_SHA256, request.content))
request.headers["x-amz-content-sha256"] = content_hash

end
content_hash = get!(request.headers, "x-amz-content-sha256") do

end
