AutoInput AutoInput The callable returned a null value

I have this problem:


That "The callable returned a null value" message pops up every time I touch device's screen.

Device info: Lenovo YB1-X90F
Android: 7.1.1

 

V 2.7.bf

And there seems to be another problem.. Autoinput Accessibility service won't stay enabled. Even tho the Accessibility in Foreground is enabled.

 

Hey, sorry about slow response!

I have one idea what could be causing this. When the tablet updated to latest version last year, Google play stopped working. I can't update apps or install Apps trough Google play. I googled around found on a Lenovo-forum that there is some special Lenovo powersaving features that prevent Google Play from working. Only reliable workaround I have found is to put the tablet in power saving mode, this seems to disable the feature that prevents Google Play from workin. Could this be cause for AutoInput not working correctly?

--------------
Apps not updating is the main reason why I was using AutoInput... I made a Task that puts Battery Saver mode on, opens Google Play and presses update all. Task does work then I manually check that AutoInput service is enabled and press run. But after a while AutoInput just stops working.
