I tried to edit a line of html code on my products page and now when I click on a product I get the following traceback.

I need to change the code from <h3>Item Number: <span t-field="product_product.default_code"/></h3>

to

<h3>Item Number: <span t-field="product.default_code"/></h3>

i can't get back to the page to edit the HTML. See video link at end of this post...

Error

Error message:

Template: 726

Path: /templates/t/t/div/section/div[2]/div[2]/h3[1]/span
