Problem With parameterized paths Hi I am also facing similar as user bflynnbyx who posted a question on 1/5/21 I have imported an openApi yaml file and created a virtual service. When testing any endpoint that has a parameterized path, readyApi's java server throws these errors: Wed May 26 10:23:42 CDT 2021: ERROR: got an exception while dispatching - returning a default 500 response Wed May 26 10:23:42 CDT 2021: ERROR: java.util.regex.PatternSyntaxException: named capturing group is missing trailing '>' near index 11 (?.*\n*.*) ^ java.util.regex.PatternSyntaxException: named capturing group is missing trailing '>' near index 11 There is no mocking implementation involved, or at least the resolved answer in that question doesn't apply here. Any ideas why this java error occurs? Solved
