TypeError: Cannot read properties of undefined (reading 'version') results in DeferredProps not loading in

[Verox001]

Version:

• @inertiajs/react version: 2.0.3

Describe the problem:

When visiting a page that uses deferred props and doing a request using useForm, the following error occurs:
"TypeError: Cannot read properties of undefined (reading 'version')"

The error results in the deferred props staying undefined, which is the actual issue.

Steps to reproduce:

1. Clone the branche I created to reproduce the issue: https://github.com/Verox001/inertia/tree/version-on-undefined
2. Run the react playground environment with the 2.0.3 core as described in the contributor guide.
3. Visit the Defer page and have a look in the console. You should see the error and the deferred props not being sent to the frontend, therefore staying at "Loading..."

The hydration problem can be ignored as it comes with the playground environment itself.
