I cannot figure out why Ninja Forms is throwing this error. Documentation does not have anything available on this error.

If I am making a form, and the field key is firstname, this error will come up and say it's not found when I go to publish it, and it corrupts my form.

Unknown Field type "" not found.

Any advice would be great. Thank you!
