Bug in the parser

[DeliciousBounty]

@RazMag
During writing an active scan, I encountered strange behavior.
Description
The code do not parse every path on the OAS file.

To Reproduce
Steps to reproduce the behavior:

1. Set the OAS file with this file.
   petstore.txt

2. rename it with .json

3. go to /swagger/sca/src/active/additional_checks.rs

4. add this function:
   `pub async fn check_idors(&self, auth: &Authorization) -> CheckRetVal {
   //// reformat get with path parameter
   let mut ret_val = CheckRetVal::default();
   for oas_map in self.payloads.iter() {
   for (json_path, schema) in &oas_map.payload.map {
   println!("PATH: {}",oas_map.path.path );
   let url;
   if let Some(servers) = &self.oas.servers() {
   if let Some(s) = servers.first() {
   url = s.url.clone();
   } else {
   continue;
   };
   } else {
   continue;
   };
   }

   }

   ret_val
   }
   }
   `

5. Check the ouput. It miss some path: ""/pet/{petId}": from example
   Expected behavior
   This code should print all the existing OAS's path. But it miss some path: ""/pet/{petId}": from example
