Unncessary pop up on load of the page

Hi there,

recently after I have upgraded the marvin JS 16.2.8 I am getting an unwanted pop up on load of the page .. While debugging i found the below error . The error was displayed in the console as below . It happens only when the sketcher is called for the first time.

 

Uncaught (in promise)

wjae: dUf:

"Failed to parse: error on line 1 at column 1: Extra content at the end of the document↵↵"j: null__proto__: b

 

Hi,

Do you use IE? I guess the Promise object is still missing when you load the page (at first time).

Most browsers supports it by default. If not, promise-1.0.0.min.js is required to complete the missing implementation.

Please, check the network traffic whether the above JS file has already downloaded when the editor appears.

I guess its loading is in progress when the mentioned error appears.
