Hi @seotoronto7
Upon checking the URL you’ve provided in Google’s Structured Data Testing Tool, we do see an error message of ‘the value provided for id must be a valid URL’ – https://snipboard.io/arWmAN.jpg
This is because the 2nd list item is showing a relative URL instead of the absolute URL.
Could you check if you have a plugin (e.g. Minify HTML plugin) that is causing relative URLs to output instead of the absolute URLs?
Often, we see problems occur in combination with another plugin or theme. The fastest way to rule out any conflict, is to deactivate all non-Yoast plugins and switch to a standard theme like Twenty Twenty.
Please test this on your development or staging site, if you have one. If not, we recommend using the Health Check & Troubleshooting plugin. This plugin has a troubleshooting mode, which does not affect normal visitors to your site.
If you’re unfamiliar with checking for conflicts, we’d like to point you to a step-by-step guide that will walk you through the process: How to check for plugin conflicts
Otherwise, you can refer to our schema API if you need to make any modifications to the schema output – https://developer.yoast.com/features/schema/api/
