Hey @Armand, can you please run `fuelup update` to update your toolchain and it will download fuel-core `v0.34.0`. Please follow these steps and you should be good to go.

```auto
fuelup self update
fuelup update
fuelup default latest

```

Also, make sure to update the chain config locally and use the [latest one](https://github.com/FuelLabs/chain-configuration/blob/master/ignition/chain_config.json)
