Hi All,

I’m trying to display pdf base64 in IFrame, but getting CSP Error,

 ![image](https://global.discourse-cdn.com/atlassiandeveloper/original/3X/a/5/a557ee2e7c1ab6e7ebb2cb4fe4cb37a0d3901e23.png)

I have read frame permissions instructions ([Link](https://developer.atlassian.com/platform/forge/manifest-reference/permissions/#frames)) but couldn’t find details for base64.

Can you please advise how to do it?

Thanks in advance

Regards Niko

Hi,

This is a problem on our end and there isn’t a workaround that I can offer at this stage for PDF files.

Here is the bug report I just raised:  
[https://ecosystem.atlassian.net/browse/FRGE-723](https://ecosystem.atlassian.net/browse/FRGE-723)

Thanks,  
Caterina
