Troublingshooting Issues > "File System Access is Not Allowed" Error Message

This error is generated when an HTML file attempts to load an asset from our server's file system. This is normally caused by using a relative or protocol-less URL for an external asset without also defining a baseurl.

These are examples of URLs that are not allowed:

//yourdomain.com/style.css
/scripts/application.js

To fix this issue, you must do one of the following:

  1. Use an absolute URL (begins in http:// or https://)

  2. Use the prince_options[baseurl] API parameter to inform us which URL to use to create absolute URLs on your behalf

  3. Use a <base> tag in your document <head>, which will also inform us which URL to use to create absolute URLs on your behalf
