Turn a gedcom file in a json one to create a visualisation 3DJS

Question

I'm trying to transform a gedcom file in json this the following code:

"Installation: The gedcom package can be added as a dependency to use in your code, or if you'd like to just use the CLI, install it globallly:

npm install -g gedcom"

and please find below the error:

Error: Illegal nesting: transition from 1 to NaN
