You need to use omitzero, not omitempty. The way it works:
-
omitempty– Don't write if the value is "empty": len(0) for arrays, slices, maps, strings, false for bools -
omitzero– Don't write if the value is zero, only works for numbers.
It's annoying that it works like this, but there isn't any way to change this to the more standard behaviour without breaking comparability. It's one of the things that will be fixed in a hypothetical unplanned v2 release. See: #120.
