GitHub Actions: Error: The process '/usr/bin/git' failed with exit code 128

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
The docker CLI can’t talk to the Docker engine — it isn’t running, or your user can’t access the socket.
GitHub Actions: Error: Cannot perform an interactive login from a non TTY device
`docker login` asked for a password interactively, but CI has no terminal — pass credentials non-interactively.
GitLab CI: Cannot connect to the Docker daemon at tcp://docker:2375. Is the docker daemon running?
A docker-in-docker job could not reach the `docker:dind` service — it is not started, not privileged, or the TLS/host settings do…
GitHub Actions: Error: Process completed with exit code 137 (Killed — out of memory)
The command was killed by the system with SIGKILL (128 + 9), almost always because the runner ran out of memory.
CircleCI: Too long with no output (exceeded 10m0s): context deadline exceeded
A CircleCI step printed nothing for 10 minutes, so CircleCI assumed it hung and cancelled it.
CircleCI: Error calling workflow: 'build'. Cannot find a definition for job named test / Config does not conform to schema
CircleCI could not compile `.circleci/config.yml` — a workflow refers to a missing job, a key is invalid, or the YAML is malforme…
Azure Pipelines: /azure-pipelines.yml: File /templates/build.yml not found in repository / Unable to find template
The YAML references a template (`template: templates/build.yml`) that Azure cannot find — wrong path, repo resource or branch.
Argo CD: ComparisonError: rpc error: code = Unknown desc = Manifest generation error (cached): kustomize build failed
Argo CD could not render the manifests (Helm, Kustomize or plain YAML) for the application, so it cannot compare Git with the clu…
GitHub Actions: Invalid workflow file: .github/workflows/ci.yml#L12 — You have an error in your yaml syntax on line 12
GitHub could not parse your workflow YAML, so no run was created — usually indentation, a tab, or an unquoted special character.
GitHub Actions: Error: Input required and not supplied: token
An action needs an input (token, ssh-key, api-key…) and the `with:` value is empty or missing — often because the secret does not…
GitHub Actions: workflow does not run on push / pull_request / workflow_dispatch button missing
