MGS3017: workspace still loading
The server holds this workspace in state LOADING: it is evaluating the
workspace's magusfiles. A call that needs the loaded workspace answers
UNAVAILABLE with this code and a google.rpc.RetryInfo detail naming how long to
wait.
[MGS3017] workspace /repo is still loading; retry shortly
Why
A load is transient, so the call is safe to retry unchanged. This is the twin of MGS3016: that one needs a person to fix a source first, this one needs only time. A load most often runs here after a source change reloads a workspace that had failed.
Resolution
Retry after the retry_delay in RetryInfo. If the retry answers MGS3016, the
load finished and failed; follow that page.
