Note

Check out our Mappings documentation to get more information on mapping functions.

Navigate to the default mapping function in the src/mappings directory. You will be able to see three exported functions: handleBlock, handleAction, and handleAction. Delete both the handleBlock and handleAction functions as you will only deal with the handleAction function.
