Render "deploy failed ... build failed" triggered from CI
Render ran your service build command and it exited non-zero, so the deploy status becomes "build failed". A CI step that polls the deploy then fails. The real error is in the Render build logs, not in the trigger.
What this error means
A CI step that triggers a Render deploy and waits for it reports the deploy finished with status "build_failed" or "update_failed".
==> Build failed 😞
==> Deploy failed for <service>: build failedCommon causes
The build command failed
A compile error, a missing dependency, or a failing step in the build command returned non-zero, which Render reports as build failed.
A missing env var or wrong build settings
The build references an environment variable or runtime that is set locally but not configured on the Render service.
How to fix it
Read the Render build logs
- Open the failed deploy in the Render dashboard and read the build log.
- Reproduce the failing build command locally.
- Fix the underlying error, then trigger a new deploy.
Configure build settings and env vars
Set the build command, runtime, and required environment variables on the service so the Render build matches local.
# render.yaml
services:
- type: web
name: app
buildCommand: npm ci && npm run build
envVars:
- key: NODE_VERSION
value: "20"How to prevent it
- Run the build command in CI before triggering Render.
- Define build settings and env vars in
render.yaml. - Pin the runtime version so Render matches local.
