- Search ssp-libraries-ext.js in the Netsuite global search and we will find a number of files so we need to open one by one to check in which file error is occuring.
2. Go to that line and comment that code or do the modification according to the need.
3. After these steps do the cache invalidation and do hard refresh in the website.
Now the error will be resolved.
