I'll be happy to help you out with this.
I have come across this error a few times and found a workaround if you happen to be using a Shopify-developed theme. This URL Parameter Query is a standard query used in many apps or features within Shopify. Our technical team has previously confirmed that the 'You may also like' product feature has an impact on the parameter. By simply turning off this feature should fix this error. It seems Facebook recently made some updates and included these parameters as unacceptable. Please follow the steps below to remove the feature:
From your Shopify admin, head to Themes > locate the theme you wish to edit.
Click Customize > select Products from the drop-down menu > click Product Recommendations and untick 'Show dynamic recommendations' then click 'Save':
If you find that the steps above make no difference, you may need to talk to Facebook. I've outlined below how you can contact them.
Merchants with an already existing Business Page on Facebook will be able to access the live chat service. (There have been some cases of live chat not functioning for all business pages, to resolve this, you may need to reach out to Facebook through email by filling out a form found through Facebook's Help Center.)
If they're unable to assist, our live support might also be able to help. While we’re not able to provide account-specific support via the Shopify Community at this time, we’d be happy to continue assisting you through live chat, email, or callback.
