When a build to XM Cloud fails, where can a developer find information to diagnose the error?

The deployment log files for the environment are the primary source of information for diagnosing errors when a build to XM Cloud fails. These log files provide detailed insights into the deployment process, capturing all actions taken during the build and deployment stages. When a failure occurs, these logs can reveal specific error messages, warnings, and other context that can help a developer pinpoint the root cause of the issue.

Additionally, the logs usually document the sequence of operations and any related messages, making them essential for troubleshooting. By thoroughly examining these logs, developers can identify what went wrong, whether it was due to syntax errors in code, misconfigurations, or other issues, which can be addressed effectively.

Other options, while potentially useful in their own contexts, do not offer the same targeted insights specific to build failures. For instance, deployment configuration files primarily detail the intended structure and configuration of deployments rather than provide runtime error information. Site performance logs typically focus on tracking and monitoring application performance rather than deployment failures. The Cloud application status page offers a broader overview of the application's health but lacks the granular detail found in the deployment log files necessary for diagnosing specific build errors.
