Getting typescript compile error on beta.0 with noPropertyAccessFromIndexSignature

[evertbouw]

Upgrading from alpha.6 to beta.0 and I'm now getting a compile error while using the noPropertyAccessFromIndexSignature flag.

node_modules/.pnpm/@[email protected][email protected][email protected]/node_modules/@reduxjs/toolkit/dist/uncheckedindexed.ts:5:46 - error TS4111: Property 'a' comes from an index signature, so it must be accessed with ['a'].

5 const testAccess = ({} as Record<string, 0>).a
                                               ~


Found 1 error in node_modules/.pnpm/@[email protected][email protected][email protected]/node_modules/@reduxjs/toolkit/dist/uncheckedindexed.ts:5

if I change that line to

const testAccess = ({} as Record<string, 0>)['a']

it compiles just fine.
