How to decode this error message?

[saicharan0112]

I am trying to generate the svg file from a yosys exported json file using the netlistsvg version that is available on the npm. I get this error but I don't understand anything. Can anyone help me understand what it says from the netlistsvg perspective please?

Here is the msg.
netlistsvg_error.log

And here is the json file.
tempsenseInst_error_yosys_json.zip

I experienced this as well. Installing the latest version from git using npm install -g [email protected]:nturley/netlistsvg.git as described in #120 fixed it for me.
