JSDefender throws parsing error for public fields?

[LRagji]

Not sure if this is the correct repo to raise this defect, but stuck on it for sometime
I have example.js file

export class Server {
    props = "abc"
}

Then i run

jsdefender --license ./example.js ./exampleO.js --estarget es2020

Which gives me parsing error as below

Now i understand that my JS file is with correct definition of ES specs: MDN then what is this parse errors...

The same error pops up for private fields as well # preceded.

Following code works:

export class Server {
    constructor()
    {
        this.props = "abc";
    }
}

What am i doing wrong?
