Cannot "Add Feed" in Feedamic Configuration

[Sm1lEE]

Hi @martyf ,

thanks for the v3 update, this looks very exciting.
Unfortunately I am having trouble to configure the addon.

Bug description

When clicking the "Add Feed" button in the Feedamic Configuration in the CP nothing happens.

Inspecting the network shows this:

Request URL: http://feedamic-test.test/cp/fieldtypes/replicator/set
Request Method: POST
Status Code: 422 Unprocessable Content

The network response is this:

{
    "message": "The given data was invalid.",
    "errors": {
        "blueprint": [
            "This field is required."
        ]
    }
}

Steps to reproduce

• create a new statamic project: statamic new feedamic-test (no starter kit, enable Statamic Pro)
• install feedamic addon: composer require mitydigital/feedamic
• go to Feedamic's Addon settings in the control panel: http://url.local/cp/addons/feedamic/settings
• try clicking the Add Feed... button in the Feeds > Configuration section
