error listing Networks: %v

Error message

error listing Networks: %v

What it means

Wrapped error from Network.Find when the Networks.Get call fails with a non-404 error. Despite the 'listing' wording it is a single-network Get against the (possibly overridden) project; fires on permission errors, wrong project, or API failures.

Solutions

  1. Inspect the wrapped error for the Google API reason
  2. Verify the network name and project (including the optional shared-project override) in the spec
  3. Ensure compute.networks.get permission on that project
