[Bug]: <Form> elements do not work in error component

[charliematters]

What version of React Router are you using?

6.4

Steps to Reproduce

https://stackblitz.com/edit/github-gkokwd-ogj8yk?file=src%2FApp.tsx

^^^ Failing example here. Replacing <Form> with <form> does at least render the page

Error in console begins with:

index.tsx:861 Uncaught TypeError: Cannot read properties of undefined (reading 'route')
    at useFormAction (index.tsx:861:15)
    at useSubmitImpl (index.tsx:799:23)
    at index.tsx:589:18

Expected Behavior

The form should load and allow submissions to the route's action

Actual Behavior

An exception is thrown which causes the whole app to disappear

Hey @charliematters - thanks for the reproduction! This was actually a bug that was just fixed in #9735 and is currently available in 6.6.0-pre.0. I confirmed fixes the provided reproduction, so I'm going to close this out.

6.6.0 is the release that will finish up the React Router-ing Remix work so it might be in prerelease a bit longer than normal as we ensure we've worked out any last kinks on the Remix side. So the stable may be after the holidays but we'll see how this week goes :)
