I can't work out how to get TangleID to work

Question

So im trying to get tangleID to work to use it on a project. I am using this project.

But everytime I try and run the code i get an error message of “Mam.init is not a function”.

I’ve tried to include the mam library as well inside then then it stops throwing an error but breaks completely by not printing out the console.log on the next line.

I found this code as well

https://gist.github.com/ender503/ecd884b07190adb79f01b0d515c3b5a3

and I’m still getting the same problem!

I'm running the sample code with following step:

Create the project directory

$ mkdir tangleid-test
$ cd tangleid-test

Paste the sample code to main.js.
Add the @tangleid/core package.

$ yarn add @tangleid/core

Run the code,

$ node main.js

If you are still getting the same problem, could you provide your Node.js version?
