I have had this happen multiple times. I have several JSON templates that I update regularly that are used across many pages on the company website. There have been times where when I have completed an update to a JSON template (adding some extra fields), some pages that utilise that JSON then return 404 errors.
A quick fix I have found is to update content on the pages that return the errors in Prismic.
Has anyone experienced this? If so any advice as to why it’s happening?
Thanks in advance!
