Hi,

Let us investigate it and get back to you soon.

I opened case #00011233 with support, and so far the probable cause seems to be: “Customized fields could be a potential cause of the error.” I discovered that I am able to upload Katalon test cases to a qTest project that has no customized fields in the test case template. However, since I am dealing with an existing qTest project with hundreds of existing manual test cases and dozens of active qTest users, creating a qTest project just for automation is not the optimal solution.
