[INF] Current version: v1.1.0

Current Behavior:

Using '-form-extraction' option, the extraction of form data is ignored when the action field of the "form" tag is set to "#".

Expected Behavior:

To fix the issue, simply replace the value "#" with an empty string ("") in extracted action field.

Suggested Fix:
To fix the problem, add the following code at line 27 of the file pkg/utils/formfields.go:

if action == "#" {
    action = ""
}
