Tanstack optimistic update for deleting a 'template'. I cant seem to figure out whats wrong..

Hi yall! At my work we have some big files called templates. They can go up to 10 mb (yes they are that big) and when deleting one it sucks for the UX. So I am implementing optimistic updates from tanstack query but I seem to be doing something wrong and my guess is because of my lack of knowledge.. Other info: - I have a TemplateProvider function that caches data under the cache key composed of an array of values ( ["templates", pageNumber, folderId || "all", search],) - I have a useRemoveTemplate() that tries to optimistically update the ui by following the tanstack docs (https://tanstack.com/query/v4/docs/guides/optimistic-updates) - I added a picture of the table that I am trying to optimistically update Problem: When I queryClient.setQueryData(cacheKey, () => deletedTemplateList); in my useRemoveTemplate() my Template provider does not recognize the new values and reads 'undefined' why? 😦 Thanks in advance for thinking along
