pull access denied for "aaaaa" repository does not exist or may require 'docker login'

After cloning a project from Gitlab on ubuntu, I tried to run it through docker, I opened a terminal, got to the directory where the .yml file was and wrote down:

I was greeted with this message:

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?

I pressed y.

Then for a few seconds, I got:

Pulling "name of the module here"

Then I was greeted with this message:

ERROR: pull access denied for "name of the module here", the repository does not exist or may require 'docker login'pedroesteves@pedro:~/Desktop/project$ 

Any help would be very appreciated. I already looked to some similar posts but none was able to help me.
