"Failed to start remote builder heartbeat"

Hi! I tried deploying my app but got this error;

virgilxw@Dunedain:~/repos/fso/part3/3.1phonebookbackend$ fly launch
An existing fly.toml file was found for app wild-night-5945
App is not running, deploy…
==> Building image
WARN Failed to start remote builder heartbeat: must provide either an organization id or app name
WARN failed to create build in graphql: input:3: createBuild Could not find App

Error failed to fetch an image or build from source: error connecting to docker: must provide either an organization id or app name


I guess the first question would be have you deployed this app before and just want to update it, or is this a brand new app? Only normally fly launch is the command for a new app. And fly deploy would be used for subsequent changes to it. Given that output says it has an assigned name and a fly.toml, that suggests it’s an existing app … in which case it may be as simple as using fly deploy instead of fly launch.

Does running fly status or fly doctor reveal any issues/errors?
