Max files requires a minimum of 2, not 1

[JohnSmall]

Using Rails 7.2, with import maps, in my erb views I have

<%= form.filestack_field :image, 'Test Filestack!', pickerOptions: { 'maxFiles': 2 }, onFileUploadFinished: 'onFileUploadFinishedCallback' }, id: SecureRandom.uuid , input_id: SecureRandom.uuid %>

If I set maxFiles to 1 it allows me to select a file, but it's never uploaded to Filestack.
