Why am I getting a 'missing parameters' error when adding products to cart?

I have several products that are “Missing parameters” when attempting to add it to the cart.

The exact wording is “Parameter Missing or Invalid: Required parameter missing or invalid: items” and the only advice it has to do is to “return to the previous page”.

I have tried to delete the certain listings then redo it and it still has the same issue. I can add new products and not have that issue at all so I am very confused on where to go from here. My theme is Dawn and the products with “missing parameters” all can be found in my “Ready To Ship” collection under “Online Store” My website is www.krisfieldesigns.com

I am not sure of what information to provide other than what I am so feel free to ask me for whatever you think may help me! I am tech savvy but websites are new to me!

Hi @K-DesignsLLC ,

Can you send me the Shopify link or check your site link again, I will try to access but have no success.

After visiting the site, I will help you check it

My apologizes, I am not sure why that isn’t working. That is normally how I give my link to others.

Hi @K-DesignsLLC ,

Please go to main-product.liquid file, find ‘product-form__buttons’ and remove ‘disabled’ here:

Hope it helps!

It seems like I don’t have disabled there to begin with!

Hi @K-DesignsLLC ,

If you turn it off and it still doesn’t work, I suggest you contact the ‘Variant Option Product Options’ app.

Because add to cart is reinstalled by the app, so the error can arise it. And it will be difficult for someone to debug it for you.

If it helped you solve your issue, please mark it as a solution. Thank you and good luck.

You have to be able to, it is probably a Cross Origin Resource Sharing (CORS) problem link… Do you have got that useful resource blocked for External IPS?

If you use automatic built-in integration Shopify with Facebook, then the incorrect value of the parameter content_ids passes to the Pixel. So you can see the issue.

Solution - to turn off automatic built-in integration Shopify with Facebook, to take the application for creating a feed for Facebook Catalog (for exampledatafeedwatch), install the Google Tag Manager (GTM), and manually set up the correct transfer value of parameters to Facebook Pixel using dataLayer and javaScript.

This is the only solution to this mistake that I know of.

This worked for me. Thanks for posting!

I have face the issue but after searching I got one thing when we create the pixel before should be must installed the tiktok pixel then the error will not come
