Uncaught SyntaxError: Unexpected token u in JSON at position 0

Question

Only at the checkout and on individual product pages I am getting the following error in the console log:

VM35594:1 Uncaught SyntaxError: Unexpected token u          


        

Answer 1

For me, that happened because I had an empty component in my page -

<script type="text/x-magento-init">
   {
   ".page.messages": {
       "Magento_Ui/js/core/app": []        
      }
   }

Deleting this piece of code resolved the issue.
