I am getting the error: ''Required parameter missing or invalid:id''  when adding a product to the cart.  I search for a solution but have yet to find a solution.  Can anyone help, please?

thanks

The error message you're encountering, "Required parameter missing or invalid: id," typically indicates that the id parameter is missing or incorrect when adding a product to the cart in Shopify. To resolve this issue, you can try the following steps:

1. Verify the product ID: Double-check that you are using the correct product ID when adding the product to the cart. Ensure that the id parameter is set to a valid product ID.

2. Check the code implementation: Review the code or script you are using to add the product to the cart. Make sure that the id parameter is properly included and passed when making the request to add the product.

thanks for the reply.  I am not sure what you mean by product ''ID''.

I tested 5 products and they all had the same issue.  However, I change my browser from Firefox to Edge and it was all good.  The issue must be coming from the Firefox browser.   Does that make sense?
