Error when uploading VoiceFlow Action to Google

Seem to be getting an error when trying to upload my action to Google.

The error I’m getting is: "Submitting Project Error - Cannot read properties of undefined (reading ‘type’)

Would this be linked to using VoiceFlow’s Alexa to Google Action converter at all?

Help would be much appreciated!
