[Bug] Prefetching issues (Cannot read property `templateLoaded` of undefined)

Reporting a bug?

Hey!

I’ve been running into an issue where I’ve been receiving this error when navigating between pages on when running a dev server:

Any thoughts on the instances in which this could even occur? Or should we be guarding against routeInfo being undefined?

I’ve currently been in the process of migrating from v5 to v6.

Oops… @krzysztof-pyrzyk-ah I see we were working on the same issue! The fix I just submitted as PR is the same as yours, but I realised the underlying issue here is that 404 route info is not handled correctly in all cases after #992 was merged. This is quite a complex issue though so I hope @tannerlinsley you could also have a look at this!

@jlee1201 Does this error break the page? In development it should be expected for your site to at least try fetching the routeInfo and templates for valid links (even if they point to nonexistent pages).
