Fix compilation warnings

[carlospatinos]

There are 46 warnings As in here: required: UpdateAction<WithKey> found: UpdateAction 46 warnings

Run ./gradlew build to see all of them

Fix all of them and make sure the project still compiles and pass all CI cycles

Can this be considered for hacktoberfest?
