'docker login': denied: requested access to the resource is denied

Hello,

When I Tried to Up the Docker container for thingworx,  I do get the following error:

ERROR: The image for the service you're trying to recreate has been removed. If you continue, volume data could be lost. Consider backing up your data before continuing.

Continue with the new image? [yN]y
Pulling postgresql-init (thingworx/postgresql-init-twx:latest)...
ERROR: pull access denied for thingworx/postgresql-init-twx, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

How can I resolve this?

Thanks,
