Hey Maxim - I would attach some logic to the onClick handler of the button, so that when you click “OK”, you read the value of the input 

@Addison Schultz 

Yeah you are right. It is possible to get the input value on setTagNameModal.html

so I stored the value in the metadata and have to get this on main.html

.then() doesn’t work on web sdk 2.0 I think

please let me know your thought

You’re working with quite a lot of nested then/promises. Are you able to work with async/await instead? 

Otherwise, you will need to include the async keyword in the first “then” call (the one right after you declare width/height (in the first line of the original screenshot you posted)
