Unexpected value of meta.initialValue

[tadeas22]

Bug report

Current Behavior

Value of meta.initialValue is null in case if path is path.to.property for object

{
"path": {
  "to": null
 }
}

const [_, meta] = useField("path.to.property")
meta.initialValue === null

Expected behavior

Value of meta.initialValue is undefined

const [_, meta] = useField("path.to.property")
meta.initialValue === undefined

Suggested solution(s)

export function getIn(
  obj: any,
  key: string | string[],
  def?: any,
  p: number = 0
) {
  const path = toPath(key);
  while (obj && p < path.length) {
    obj = obj[path[p++]];
  }

  // check if path is not in the end
  if(p !== path.length && obj === null)
    return undefined

  return obj === undefined ? def : obj;
}

We are experiencing the same problem.
However, this does not only apply to nulls.
But for all the falsy:

Maybe I suggest this solution :

export function getIn(
  obj: any,
  key: string | string[],
  def?: any,
  p: number = 0
) {
  const path = toPath(key);
  while (obj && p < path.length) {
    obj = obj[path[p++]];
  }

  // check if path is not in the end
  if(p !== path.length && !obj) {
    return def;
  }

  return obj === undefined ? def : obj;
}
