Looks like version compatibility issue. Use latest version of qaf 3.1.0-RC2 with testng 7.4.0.

Updating version will fix above error, still you will see issue related to step. The reason is following steps:

@QAFTestStep(description="click on Google Search button") //missing argument placeholder 
   public void clickOnGoogleSearchButton(List<String> s) {
      System.out.printf("List: %s\n", s);
   }
           
@QAFTestStep(description="search result page should generate")//missing argument placeholder
   public void searcgResultsShouldPopulate(List<String> s) {
      System.out.printf("List: %s\n", s);
   }

If your step (method) has arguments, step description need to have argument placeholder and those arguments needs to be passed where step called. See the example below:

@QAFTestStep(description="click on Google Search button")
   public void clickOnGoogleSearchButton() {
      System.out.printf("clickOnGoogleSearchButton");
   }
           
@QAFTestStep(description="search result page should generate {results}")
   public void searcgResultsShouldPopulate(List<String> s) {
      System.out.printf("List: %s\n", s);
   }

feature file:

Feature: Text box validation

Scenario: Validate google search text box

   Given user is on google Web Page
   When user enters text 'DNA' in google search box
   And click on Google Search button
   Then search result page should generate ["a","b","c"]

Updated QAF to version 3.1.0-RC2 added testng 7.4.0. It working fine now — TechService, Feb 04 '22 at 14:02
