Using the Pulumi CLI against an existing stack running

pulumi config refresh

results in an error:

no previous deployment

This stack has resources that were created that are less than 24 hours old.

Have you changed your login? Maybe you need

pulumi login

again, maybe with different values?

Not really sure, but this seemed to be an issue with having pending resources in the state (potentially an interrupted pulumi run) that failed to sync the pulumi config. i was able to recreate the config manually to get the stack back into a healthy working state.
