Hello,

Thank you for your post.

I would recommend debugging to identify which line of code in the script is hitting this error.

Comment out code until the error stops. Once the error is gone, uncomment out the last line commented out and see if the error returns. If it does, then you've confirmed which line is hitting the error.

Once you've identified which line of code is creating the the error, please let us know.
