Issue with Docusign JS for production embedded signing due to Content Security Policy

Hello,

 

I’m getting the following error when trying to use Docusign JS for production embedded signing.

I have set the frameAncestors to be http://localhost:8080 and https://apps.docusign.com when calling the API to create the embedded signing view URL.

The same setup worked with the demo integration where the frameAncestors had https://apps-d.docusign.com.

Could you please help me resolve this issue?

 

Error Message:

Framing 'https://apps.docusign.com/' violates the following Content Security Policy directive: "frame-ancestors 'self' https://ca.docusign.net". The request has been blocked.
