With get there's no need to check if errors exists. You can also pass the fallback value as the third argument.
Suggested change
| error: errors ? get(errors, field) : null, | |
| error: get(errors, field, null), |
Please do the same in the two lines below.

set mutates the object you pass as the first argument, so this mutates the previous state, which should be avoided. Instead, please pass an empty object as the first argument:
Suggested change
| ...set(state, payload.field, payload.value) | |
| ...set({}, payload.field, payload.value) |
Please do the same on other set calls you have.

I'm not sure about this... What if you have a field in the form named active?
What do you think about keeping the meta object as a flat object with keys with dots? Like this:
meta: {
'foo.bar': {
active: false,
// etc
}
}Let's discuss this on Monday, ok?
