Cannot publish data - please advise

I have searched and searched for how to resolve my problem of not being able to publish my data, but nothing seems to be working...

I have collected data on ODK Collect and uploaded it to Aggregate online. I have turned on the relevant API keys and it seems that my credentials (OAuth 2.0 and my API key) are registered correctly in ODK Aggregate. Yet when I go to 'publish' my data, I get this message:

Can anyone please help me on this? I'm entirely stuck. One point of note is that when I went through my aggregate set up it didn't ask me for my email as the final step. Not sure if this is relevant?

Many thanks!
