Expected behavior

No error

[dapplion]

This e2e test still relies on an external provider. This is a no-go but we never had the time to fix it since setting a local EL with deposits is a lot of hassle. Maybe @nazarhussain could you do some preliminary assessment if this is doable without to much effort?
