ACL Pathing not working for /robots.txt

This is driving me insane. ACL and path should be really simple but for some reason, HAproxy is not matching the ACL for path.

Local testing input: curl -k https://localhost/robots.txt --header 'Host:' -A "Robot"
Current results: http denys

403 Forbidden

Request forbidden by administrative rules.

Expected results: show the robots.txt file and not the 403.

Here is my config without the PII attached

We have an ACL that looks for “bots” in our user agent string and if it’s not a list of “good” bots we want Crawling, we want to block it from going further. Hence in my example with the User-Agent “Robots” shoudl satisify that result.

Any help would be appreciated. Thanks
