Problem with Google Compute plugin

Hello,

I'm wondering if anyone else has noticed this problem too, or has a
workaround?

I'm trying to create a new host via GCE compute resource. If I enable
External IP option in VM tab, I'm getting: "Invalid value for field
'resource.networkInterfaces[0].accessConfigs[0]': ''. Specified
external IP address not found."

This is also reported in Bug #14132: Cannot provision GCE instance with external IP flag - Foreman
