Exception when executing PrepareNoProjectTm: Unexpected exception when configuring file multiFileConverter for task 'Word Count': Object reference not set to an instance of an object..

Hi all,

I'm using SDL Trados 2017 Project Automation API.  The code is working fine in creating project using template, adding files, scanning files, and converting to translatable format.  But when it got to Word Count, the exception occurred.  When I opened the project using SDL Trados Studio 2017, and looked at Task History of the project, I can see this error:

 

Can someone help me debug this issue?

 

Thank you!
