CI/CD Pipeline Failing on Cursor-Generated Code
Code that Cursor generated works locally but fails your CI/CD pipeline. GitHub Actions, GitLab CI, CircleCI, or another automation platform reports lint errors, type check failures, broken tests, or build errors on code that runs perfectly on your development machine.
This is a common disconnect between AI-assisted development and automated quality gates. Cursor generates code that compiles and runs but may not pass strict linting rules (ESLint, Prettier), type checking (TypeScript strict mode), or existing tests. The development experience is smooth because you might have less strict local settings or skip running the full test suite.
The pipeline failure blocks deployments and forces you to retroactively fix issues that could have been caught earlier, often requiring multiple fix-and-push cycles that slow down your delivery.
Error Messages You Might See
Common Causes
- Linting rules stricter in CI — CI runs ESLint/Prettier with the project's full rule set, while your local editor might have relaxed settings or auto-fix on save that masks issues
- TypeScript strict mode in CI only — The pipeline runs
tsc --noEmitwith strict settings, catching any types, unused variables, and implicit returns that Cursor generates - Missing test updates — Cursor changed implementation code but didn't update corresponding test files, causing test assertions to fail
- Different Node/Python/runtime version — CI uses a specific runtime version that differs from your local environment, causing syntax or API incompatibilities
- Missing environment variables — Build-time environment variables available locally aren't configured in the CI environment
- Import path case sensitivity — macOS file system is case-insensitive but CI Linux runners are case-sensitive, so
import './Components/Header'works locally but fails in CI
How to Fix It
- Run the full CI checks locally before pushing — Add a script like
"ci": "npm run lint && npm run typecheck && npm run test"to package.json and run it before committing Cursor's changes - Fix linting issues with auto-fix — Run
npx eslint --fix .andnpx prettier --write .to automatically resolve formatting and style issues - Match local and CI runtime versions — Use .nvmrc, .python-version, or .tool-versions to pin the same runtime version locally and in CI
- Configure Cursor rules for your project — Add a .cursorrules file that instructs the AI to follow your linting rules, use strict TypeScript types, and maintain consistent import casing
- Add pre-commit hooks — Use Husky and lint-staged to run linting and type checking on staged files before each commit, catching issues immediately
- Check import path casing — Verify all import paths match the exact file/directory casing. Use ESLint plugin
eslint-plugin-importwith the no-unresolved rule

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job.

Get HelpFrequently Asked Questions
How do I make Cursor follow my project's linting rules?
Create a .cursorrules file in your project root with instructions like: 'Follow ESLint and Prettier rules. Use TypeScript strict mode. Never use any type. Always add return types to functions.' Cursor will reference this file when generating code.
Should I fix CI failures manually or regenerate with Cursor?
For simple lint/format issues, run the auto-fix tools (eslint --fix, prettier --write). For type errors or test failures, it's often faster to fix manually than to prompt Cursor again, as AI may introduce new issues while fixing old ones.
