Removing package.json in favour of deno.json has lost me some types

I figured having a mix of both was slightly mad so I moved all my imports and tasks to deno.json

I’ve run deno update, running 2.6.1

Is there an extra step I’ve missed to ensure everything resolves as it did before?

I did see others had experienced this in an earlier version (~2.1 ish) and a fix was planned but I couldn’t see a resolution in the thread.
