@aristosMiliaressis looks very useful.

we can keep the inconsistent request method in the output uniform following CAPS for the method.

Current:

cat output | jq '.response.forms[].method' | sort -u

"GET"
"POST"
"get"
"post"

Expected:

cat output | jq '.response.forms[].method' | sort -u

"GET"
"POST"
