Hello,
same answer to you like for the last 20 new joiners who do not read and directly post at the forums
We got sticky threads (at the top of each forum) for you explaining how to read the error messages, what to do then and where to report them to.
In your case please directly post at the addon comments (and read thsoe first if anyone else got that error and reported it already then you do not need to repeat it unless you can share more info):

This helps the addon devs. to find your error reports more easily.
Thank you for reading before posting next time, if joining any forum.
