Frontier node template fails to build

Question

I've just checked out the latest frontier version from master branch (28c4bce). When I'm trying to run ./node-template-release.sh I'm getting the following error. How to fix this?

Answer 1

In the First one there is missing

Type Event = Event 

and in the second , there is missing MaxcodedLen in the Struct RawOrigin in your code
