🐛 BUG: Incorrect error when applying local migrations with d1 "Cannot read properties of undefined (reading 'map')"

[seveibar]

What version of Wrangler are you using?

2.6.2

What operating system are you using?

Linux

Describe the Bug

When the migration fails, I get the error Cannot read properties of undefined (reading 'map') when trying to do wrangler d1 migrations apply my_db_name --local

After fixing the issue with the migration, there is no error.

When you migrate without --local, you get the proper error:

This might be fixed with the latest version of the shim in miniflare (CC @mrbbot)

Hey! 👋 Yep, I'm in the process of revamping the D1 Miniflare integration to use the shim. This should help alleviate some of these issues once implemented.

Hmmm, looks like this isn't quite fixed by #2717, this is the output I'm getting now:

I guess we'll need to extract the cause if the error has one.

Hey! 👋 This should've be fixed by #2838 👍
