[17:58:04] [CRITICAL] all tested parameters appear to be not injectable. Try to increase '--level'/'--risk' values to perform more tests. Please retry with the switch '--text-only' (along with --technique=BU) as this case looks like a perfect candidate (low textual content along with inability of comparison engine to detect at least one dynamic parameter). Also, you can try to rerun by providing either a valid value for option '--string' (or '--regexp') If you suspect that there is some kind of protection mechanism involved (e.g. WAF) maybe you could retry with an option '--tamper' (e.g. '--tamper=space2comment')
