request to http://${host}/computeMetadata/v1/instance/service-accounts/default/token?scopes=

Hi,

I am getting an error 'request to http://${host}/computeMetadata/v1/instance/service-accounts/default/token?scopes=https%3A%2F%2Fwww.g... failed, reason: connect ECONNREFUSED 169.254.169.254:80' when trying to perform query job on BibQuery.

I would like to introduce retry logic for this kind error. What is the error code thrown from BigQuery API for the this ECONNREFUSED error?
