I am getting an error in Odoo 9 Community whenever I try to print any report (PDF) from the backend. Error confirmed to occur for sale, invoice, purchase, and delivery reports. This only happens in Chrome - it works without errors in Firefox.


Despite the error, the reports DO still print normally.

I do have web.base.url set in the System Parameters and I don't have any other odd behaviors.


Error thrown by Odoo is:

Odoo Client Error:

Uncaught SecurityError: Failed to read the 'contentDocument' property from 'HTMLIFrameElement': Blocked a frame with origin "http://my.domain.com" from accessing a cross-origin frame.

http://my.domain.com/web/static/src/js/framework/ajax.js:231

Traceback:

Error: Failed to read the 'contentDocument' property from 'HTMLIFrameElement': Blocked a frame with origin "http://my.domain.com" from accessing a cross-origin frame.

Error thrown by Chrome Console:

Refused to display 'http://my.domain.com/report/download' in a frame because it set 'X-Frame-Options' to 'DENY'.


Uncaught SecurityError: Failed to read the 'contentDocument' property from 'HTMLIFrameElement': Sandbox access violation: Blocked a frame at "http://my.domain.com" from accessing a frame at "null".  The frame being accessed is sandboxed and lacks the "allow-same-origin" flag.


Why is this error being thrown and how can it be fixed?

This issue fired when you try to call ajax to another domain, please check this article for more info about Same origin policy. Please check the link below.

I looked into that issue and I dug into the Chrome Developer Tools to see the domain trying to be referenced. Only domains I found were the Odoo domain (good) and an empty domain, which I assume is the source of the problem. However, I have no idea why it would only cause errors in Chrome and no errors in Firefox.
