Can not run a new testcase

Hi everyone,

I am learning and following the API Testing with Katalon Course, I followed the guideline: Adding the api request to Test case but unfortunately, when I click Run testcase, I always meet the error message like an image below and can not run any testcases. Is there any ideas to resolve this issue?

Hi Thao, :wave:

Welcome to our forum. I will be looping in my colleagues @xuan.tran and @Elly_Tran so that they can take a look at this issue and get back to you soon.



Can you please give us the full error log as well as the request you are calling? Please ensure that the endpoint URL, request method (GET, POST, etc.), and any required headers or parameters are defined accurately.
