Hi Mounika, 
 
We are unable to reproduce the reported issue at our end in our latest version(18.1.46). We have created a simple layout sample and while run the sample,  diagram nodes gets properly loaded without any console error. So could you please upgrade your version to our latest version. 
 
 
In case if the issue still persists, in our latest version please share us video demonstration of illustrating the issue or modify the above sample illustrating issue which would help us to serve you better.
