I am trying to build the Frontier Node Template from this code or from the Frontier repository.

But when running the cargo build --release I am getting the following error:

 error: non-defining opaque type use in defining scope

Finally I was able to compile it. I am not sure what was causing the error, but this is what I did:

I updated the rust toolchain:

rustup update

Check i was in the last commit, delete the Cargo.lock and:

clean cargo
cargo build --release 

And it worked!
