API Testing how to check value of Array

Hi, When testing an REST API, I get an response, i need to check a keywords where name=“TestName” but it throws below error
Expected element property value ‘TestName’ is not equal with actual property value ‘[null, null, “Abc”, “nameTest”]’

I need to test specific value is present in that response or not.

Is there any possible to test above scenario.
Thanks in advance.
