@divyeshbhalekar looks like you are using an old version (1.37.3). Try the current version (1.40.2): https://github.com/slimtoolkit/slim/releases/tag/1.40.2

The top level error in your post (docker event stop chanel is nil) is related to an old concurrency bug and shouldn't be there anymore. It is curious to see the broken pipe error with the docker socket, but let's see if you get more luck with the latest release first.

@kcq still getting the error i am using the version you specified (1.40.2):

      i have attached my entire pipeline 

[kcq]

Now that we have the current version let's see what kind of errors you are getting now... It'll be good to add extra debug flags (global --debug flag and --show-clogs build command flag): /dist_linux/slim --debug build --show-clogs --tag gcr.io/${{ env.GCP_PROJECT_ID }}/${{ env.SERVICE_NAME }}:${SLIM_TAG} --http-probe=false ${{ steps.meta.outputs.tags }}
