I am developing a plugin using web api, where I read the miro board contents from javascript:

Sample code:

async function javascriptFunction() {

          let selectedWidgets = await miro.board.selection.get() 

}

This code works fine first time, but when the app is launched again, it gives error: 

Uncaught (in Promise) TypeError: cannot read property 'selection’ of undefined.  

Anyone else faced this issue?
