"SystemError: NULL Object passed to Py_BuildValue" Delay() in Python

Am I writing my functions incorrectly? What is causing this? This is causing my tests to fail inconsistently. Thanks

    Refer to Using WaitNNN Methods in https://support.smartbear.com/testcomplete/docs/app-objects/common-tasks/waiting-process-or-window-activation.html . There are existing methods which you can use, to wait for an object to exist and timeout after a number of seconds.

    Delay and aqUtils.Delay methods work fine.

    Without seeing your actual code, it's difficult to provide help

As per https://support.smartbear.com/testcomplete/docs/keyword-testing/reference/misc/delay.html Scripting Analogue section hints to https://support.smartbear.com/testcomplete/docs/reference/program-objects/aqutils/delay.html method.

It should work as you have it; however, try using aqUtils.Delay(ms, Str)

I have created a new project to try it out and in a long loop, and it worked properly.

I tried the following variations:
1. Delay(100, "Message")
2. aqUtils.Delay(100, "Message")
3. import time
    time.sleep(100)

Perhaps it is failing due to your project sequence of events or state, and that would be hard to fix. I suggest you try the same and use what ever works for you starting with a reboot.

    Same thing is intermittently happening with aqUtils

      As it is intermittent, this means syntax is correct and the function works.

      I am not Python guy, but to help isolate the failure root cause, can you make it fail in a new empty project? or can you provide a routine that consistently demonstrate the problem.

      1. Reboot
      2. Create new project
      3. Add the following functions, change the numbers as needed, and run
      def Test2():
    Var1 = 1
    Log.Message("Started")
    for Var1 in range(1, 100, 1):
        Delay(100, "Message")
    Log.Message("Finished")

def Test3():
    Var1 = 1
    Log.Message("Started")
    for Var1 in range(1, 100, 1):
        aqUtils.Delay(100, "Message")
    Log.Message("Finished")

      If it fails contact support. If it succeed as I expect, it points to your project or the specific routine.
