Currently, in the hotstuff_handler.go file, we're calling a method on a variable m without first checking if m is nil. Specifically, in the line with if m.shouldElectNextLeader() {, if m is nil, this will cause a runtime panic.
Solution
To prevent this, we can add a nil check before calling the method. So, instead of if m.shouldElectNextLeader() {, we can use if m != nil && m.shouldElectNextLeader() {. This will ensure that the method is only called if m is not nil, preventing a potential runtime panic.
What This Pull Request Changes
This pull request adds a nil check before a method call in hotstuff_handler.go to prevent a potential runtime panic.
