An image does not exist locally with the tag

Firstly let me state I am VERY new to using Gitlab and Docker.

I am running a POC or Sandbox for my company and trying to run a simple “Hello World” Java application (Spring Boot) using a gitlab-runner and DinD.

When i commit the initial chunk of code and resources “Auto-Devops” kicks off the job, and pulls the image, but sends me the following error:

Status: Downloaded newer image for gliderlabs/herokuish:latest

The push refers to repository [gitlab.************.com:*****/root/spring-demo-one/development]```
An image does not exist locally with the tag

which is strange, because it is pulling Docker:DinD to run the project?
I dont have any locally stored images for this project because it is new, so i am confused how to proceed with this.
