Error: Compatibility Issue with parity_scale_codec::Encode and Block Serialization

[sulaman0]

I'm using Tag V1.8.0, and when I initiate the Substrate validator-set pallet in my runtime, I encounter the following errors:
^^^^^ the traitparity_scale_codec::Encodeis not implemented forBlock<Header<u32, BlakeTwo256>, UncheckedExtrinsic<MultiAddress<AccountId32, ()>, RuntimeCall, MultiSignature, ...>>``

Block Serialization Error:
Another error is thrown stating:
Block Serialized is not implemented.

These errors occur consistently, and it appears to be related to codec or serialization compatibility in my runtime configuration.

Which Polkadot SDK release are you using in your runtime? The tag v1.8.0 is only compatible with v1.8.0 release of the SDK.

Yes @gautamdhameja , I'm using v1.8.0. I found that if any pallet is missing a parameter implementation or if the fp-rpc implementation is incomplete, it starts throwing the "Block Serialized is not implemented" error.

One more question: Do you know which Substrate validator set is compatible with polkadot stable2407?
