Using bypass fqdn option on a delivery service requires http(s) in the form field

[G4m30v3r-p]

This results in bypass error of:
Issue another request to this URL: 'http://http:0/foo'

• getaddrinfo(3) failed for http:0
• Couldn't resolve host 'http'

please remove the http(s) requirement on form field

+1. That field is called http_bypass_fqdn not http_bypass_url. The field should contain an FQDN and not a URL, so we should NOT have a restriction on http(s)://

The current work-around is to edit the field directly in the database.

This is a problem with the form validation in Traffic Portal, but I just checked traffic_ops_golang and didn't find any validation of httpBypassFqdn there either. So, this is really a 2-part fix:

1. Change the pattern validation in TP to match a valid FQDN (rather than a URL)
2. Add API validation in traffic_ops_golang to ensure it's a valid FQDN
