Missing form configuration. Required: List Id, Form ID, Email Field.

Hello at CF7,
in a form it shows:
“Missing form configuration. Required: List Id, Form ID, Email Field.”

The form fields are:

<label>[text* nachname class:required  placeholder "Name*"]</label>

<label>[email* your-email placeholder "E-Mail*"]</label>
