Error in gitlab fatal Couldn't find remote ref

Question

I have created a runner and set up a pipeline for my master repository in production. While running the pipeline I am facing an issue saying fatal: Couldn't find remote ref.

fatal: Couldn't find remote ref

I have tried to clone from Linux it is working also I have checked the connection. Can anyone have any idea how to proceed?
