Weflow not passing Hubspot form ID

Question

I am passing form submission from Webflow to Hubspot, and I need to pass the Hubspot form ID so it will be linked to a specific form in Hubspot. Same is implemented on all pages but it doesn't work only on one page, and I can't figure out why. Here is the code in before body tag that passes the information (I replace the domain in the code with example.com). The Hubspot form id is placed in the form with custom attribute "data-hubspot-form-id" and the value as the form number.

I copy/ pasted exactly the same code from another page where all is working correctly but still, when the form is submitted, the hubspot-form-id is  empty.
