How can I replace the value if the key name is with a dot?

[andrew-clear]

As I understand, I can replace value via this command:
json -I -f test.json -e "this.name='andrew'"
But how can I replace a value for this key -> last.name?
I mean when I try to replace the value via this command
json -I -f test.json -e "this.last.name='andrew'"
I got:

undefined:3
this.last.name='andrew'
              ^

TypeError: Cannot set properties of undefined (setting 'name')
