Error when running the helloworld.py example file.

[ChristopherMassa]

Dear sir,

I have downloaded the modules and python files required to create Tecan scripts. However when running the helloworld.py python script with as worktable_template filename a worktable ewt file created in Evoware Standard, I get following error:

AttributeError: 'NoneType' object has no attribute 'by_index'. In attachement I have put the printscreens showing the error.

Would you please help me solving this issue? I thank you in advance,

Kind regards,

Christopher Massa
