Fast 48hrs!!! Topcoder Direct - Fix Struts Params Issue

Recently, we have made some upgrades for direct app
1. Upgrade the struts version to 2.3.31 (https://github.com/appirio-tech/direct-app/commit/39255ba8945d4bf07480458b29f833484683fd05)
2. Update the regex pattern for excluding parameters (https://github.com/appirio-tech/direct-app/commit/d162526264d4af11130a5244e91ae06e1fa797cb)

After upgrading, most actions are working properly, except some, like 

1. Challenges I created  (https://cockpit.cloud.topcoder.com/direct/my/createdChallenges.action)
2. All Challenges (https://cockpit.cloud.topcoder.com/direct/my/challenges.action)

When debugging a bit, looks like the problem is mainly because the parameters are not properly set into the action, so when the backend calling the direct api service, it is not passing the proper parameters.

For Reference, please check 

1. js code trigger the ajax call - https://github.com/appirio-tech/direct-app/blob/dev/src/web/scripts/search.js#L921-L1064, if you check in network call, you can see the parameters are properly passed.
2. actions related 
- https://github.com/appirio-tech/direct-app/blob/dev/src/java/main/com/topcoder/direct/services/view/action/my/MyCreatedChallengesAction.java
- https://github.com/appirio-tech/direct-app/blob/dev/src/java/main/com/topcoder/direct/services/view/action/my/MyChallengesAction.java
- https://github.com/appirio-tech/direct-app/blob/dev/src/java/main/com/topcoder/direct/services/view/action/ServiceBackendDataTablesAction.java


For Debugging, you can enable the struts dev mode, like update the following line in struts.xml

<constant name="struts.devMode" value="false"/>

You can also look at the server.log of jboss beside the console log.

The goal of this challenge, is to analyze the root cause and fix it. Since the direct api service is not available in local setup, you just need to demonstrate that the action can properly build the service url properly in 

buildServiceEndPoint(params)
