Runtime error: assignment to entry in nil map

Question

I am trying to generate a map and then convert that to a yaml file like this:

uid :
      kasi:
        cn: Chaithra
        street: fkmp
      nandan:
        c

@Makpoc already answered the question. just adding some extra info.

Map types are reference types, like pointers or slices, and so the value of m above is nil; it doesn't point to an initialized map. A nil map behaves like an empty map when reading, but attempts to write to a nil map will cause a runtime panic; don't do that. more info about Map
