I'm using an external docker REST endpoint. I can create, tag, remove, etc images.

When I attempt to pull or push images from a private repository on Docker Hub, I get the following errors:

[Docker] INFO: Pulling image oneplace/edu-api:latest
[Docker] INFO:

Unknown macro: {"status"}

[Docker] INFO: {"errorDetail":

Unknown macro: {"message"}

,"error":"Error: image oneplace/edu-api:latest not found"}
[Docker] ERROR: command 'Pull image' failed: {"errorDetail":

Unknown macro: {"message"}

,"error":"Error: image oneplace/edu-api:latest not found"}

or

{{[Docker] INFO: Sucessfully created image oneplace/edu-ui:latest
[Docker] INFO: Pushing image oneplace/edu-ui
[Docker] INFO:

Unknown macro: {"status"}

[Docker] INFO: {"status":"Buffering to Disk","progressDetail":{},"id":"0b16d5e541a6"}{"status":"Image push failed","progressDetail":{},"id":"0b16d5e541a6"}{"errorDetail":

Unknown macro: {"message"}

,"error":"Error pushing to registry: Authentication is required."}
[Docker] INFO: Done pushing image oneplace/edu-ui}}

In either case, the cause seems to be failure to authenticate. The credentials for repository are provided when configuring Push Image, but they don't seem to be used.
