Ran into this perplexing edge case so I thought I would share.
I have a Footer symbol that is used site-wide. Inside of that footer symbol is a collection linking to new collection items. Placing collection inside of symbols is something I do regularly for menus, nav, footers, and so on.
Today I was trying to add or replace the collection in the footer when I kept running into this error.
Sorry, you can’t add a Collection List to a Symbol that’s used on a utility page.
There are three utility pages, Password, 404, and Search Results. I immediately went to the Search Results page since that’s where I’d been working most recently. That’s when I realized the Footer symbol was there. Of course I want the footer to be on the search results page, but in order to figure this error out I removed it from the page.
Then I went back to the other page where I was working. Opened the footer symbol and was able to place the collection list into the footer with no error. Out of curiosity I went back to the search results page and tried to add the footer symbol back in. It worked. No errors.
So my two-part question to @webflow is this, what is the purpose of this error if it is easily bypassed and is the work around creating issues with the published site?
