Hi, I am building a blog where the user can write an article and see it when he clicks on it. i made a form, a page where I can see all my articles (works pretty fine), and a page where he can read the article. The thing is, when I click on the card to see the article, it brings me an unexpected null value from a parameter I used to have the collection info i need.
I have a collection call cards. On my page, I did a parameter call cardRef →documentReference → cards. Then on the first widget I did a collection reference to get my collection cards, and it gets its reference from the parameter.
I don't know what NULL, I checked every variable and I made sure to leave nothing empty.
