SyntaxError: Unexpected token ?

I ran "node ." and got the following error:

`ZRMconnector/connector.js:102
let paper = papers[title] ?? { title }
^

SyntaxError: Unexpected token ?

I'm unsure if this is my fault in setting up the connectors.json or if this is a error in the main code. Any ideas?

yeah you need at least node 15 to run this one
