Issue with HTTP API Autodeployment – VPC link error

I had not updated my HTTP API Gateway in some time. I tried to make a change today to my dev stage which uses autodeployment, and I see this message:
Deployment attempt failed: Vpc link bwk5ve was not found in account

The thing is, I do not remember ever creating a VPC link. The server the API Gateway forwards requests to has a public IP address. There are no NAT gateways, load balancers, etc. The API Gateway is functioning normally.

The list of VPC links is empty – so there appears to be a ‘ghost’ reference to a VPC link and now I cannot autodeploy any changes.

How can I fix this please?
