Seeing this error

We still dont understand which block it is you are trying to load, and are you sure it is our plugin which is the problem ?

Every block that uses woocommerce is not working, Every block that involves displaying a product.

Yes, it is your plugin causing the issue. I have tested it by disabling all plugin except yours and the problem is still there. Once your plugin is disabled, the problem goes away.
It seems to be conflicting with Woocommerce Gutenberg blocks

We dont have any conflict with standard WooCommerce as I see it, try to see here:
https://capture.dropbox.com/aNN6h4kp5rxg7o82

At our end everything works, so in order to help you could you create similar video, so I can see which blocks it is you have problems with, on where and so on.

Also maybe open your Developer tools with the tab on Console, so I can see the conflicts there.

Hi, we are seeing the same issue when trying to use the “hand picked products” woocommerce block on a page – “Error loading block: The response is not a valid JSON response.”

This is when using the Storefront theme, Woocommerce, and Beetle Tracking only (no other plugins). Deactivating Beetle Tracking resolves the issue.

I have also created a completely fresh install with just 2025 theme, Woocommerce, and beetle tracking – same issue when Beetle Tracking is activated.?

I can share the login if you like.

Thank you @djdanj that comment and video helped a lot. I have just shipped a new version which fixes this.
