The trait bound is not satisfied

Question

I am using staking-pallet in my runtime here , added all the requirements and after that I try to check dependencies using cargo check -p node-template-runtime --release this command but I'm getting this issue.

the trait bound Runtime: SendTransactionTypes<pallet_election_provider_multi_phase::Call<Runtime>> is not satisfied

The code is here

Someone please help. Thank you!

As the error said.

You missed this.

https://github.com/paritytech/substrate/blob/ae1a608c91a5da441a0ee7c26a4d5d410713580d/bin/node/runtime/src/lib.rs#L1314-L1320

impl<C> frame_system::offchain::SendTransactionTypes<C> for Runtime
where
    RuntimeCall: From<C>,
{
    type Extrinsic = UncheckedExtrinsic;
    type OverarchingCall = RuntimeCall;
}

Why?

Because it requires the SendTransactionTypes trait bound.

pub trait Config: frame_system::Config + SendTransactionTypes<Call<Self>> {
