Panopto CORS Setting Prevent Link Validation

    When using the block, link validation fails in the Block Editor, displaying:

    "Invalid url. Please enter a valid Panopto video or playlist embed url"

    Looking at the browser console, it looks like CORS rules on the Panopto side are preventing the request from completing successfully. The error I’m seeing is:

    Access to XMLHttpRequest at 'https://[REDACTED].hosted.panopto.com/Panopto/pages/embed.aspx?id=[REDACTED]' from origin '[REDACTED]' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

    When published, the video displays as expected- it’s just in the block editor that things are broken.
