Hi can you give us the log file under Help > Error Log, it’s more verbose and hence more helpful. The message displayed on the UI may have been cut short.
I actually found the reason when i was reviewing the last reply ,the two testCases ids are not the same , the first one is an older one and the second is a newer one i added now ,how did this happen ?
Some of my testcases names started with an uppercase letter and some of them started with a lowercase letter , inorder for the test cases to look more organized i had to change them
Since we can’t change the name from lowercase to uppercase in katalon (they are considered as the same) i did it manually by changing them in the declaration folder ,and forgot to change them in this testsuite
but the exception is still weird because it’s empty
