Search build logs
Search a build's log output to find the failed step.
When a build fails, the logs show you exactly where and why. You can search through any build's complete output to pinpoint the problem and fix it.
Build logs are kept for 30 days, so you have time to investigate and troubleshoot without pressure.
Open Logs in the sidebar.
Select the deploy; every build keeps its full log output for 30 days.
Each build's full output is preserved, so you can always return to past deployments to understand what went wrong.
Warnings and errors are highlighted; click a line to expand that stage's output.
Expanded output shows the complete context for that stage, making it easier to spot the root cause.
What's next
Once you've identified the failing step, review your build configuration or code to address the issue and re-run the build.
