Problem With parameterized paths

Hi, 

 

I have a simple REST API that exposes an operation to get an account as follows

 

GET /accounts/{account_id}

 

I have created a virtual API based on this API. While I can exercise actions with non-parameterized paths when I invoke the above action I receive a 500 response. 

 

Here is the request:

 

GET http://localhost:8088/accounts/1234 HTTP/1.1
Accept-Encoding: gzip,deflate
Authorization: *****
Content-Length: 0
Host: localhost:8088
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.5.2 (Java/15)

 

And response:

 

HTTP/1.1 500 Server Error
Date: Tue, 05 Jan 2021 12:16:33 GMT
Transfer-Encoding: chunked

 

I can see the following error in the error log:

 

  • Tue Jan 05 12:16:33 GMT 2021: ERROR: got an exception while dispatching - returning a default 500 response
  • Tue Jan 05 12:16:33 GMT 2021: ERROR: java.util.regex.PatternSyntaxException: named capturing group is missing trailing '>' near index 10 (?.*\n*.*) ^

Is this a known issue with REST APIS?

Re: Problem With parameterized paths

Hi,

I'm assuming this is more of a mock API issue rather than a SoapUI issue.

I'd look at the mock implementation that validates an id because of the thrown exception....

  • java.util.regex.PatternSyntaxException: named capturing group is missing trailing '>' near index 10
  • (?.*\n*.*)
  • ^

I haven't used SoapUI/ReadyAPI mocking functionality, so I'm not best placed to comment.  Some code snippets/screenshots of the validation may help someone else help you.

 

Good luck,

 

Chris
