Cannot create session after closing it

[Anonymous]

As per engima's documentation, I create the sesion via:

    const session = enigma.create({

       schema,

       url: <some url>,

       createSocket: url => Websocket(url, {<authorization header>})

    })

I was able to connect to qlik engine, open a document, etc.

I store this session in some variable and inside one function I close it:

    session.close().then(() => console.log('Session closed properly'));

Then, after a few seconds, I tried to run my application again.  However, this time, I cannot create a connection, I'm getting the error:

    {"jsonrpc":"2.0","method":"OnLicenseAccessDenied"...

So I need to wait for 5 minutes before I can run again my application.

Could you advise what is happening?  I really thought closing the session will allow me to create another session.  By the way, I am connnecting to 5 apps, so I have 5 sessions when I start my application.
