A successful build command does not guarantee a deployable result. Meridian can reject a build when the configured output directory was not produced.
- Read the deployment log and record the missing directory.
- Compare the build command and its output with the project’s own configuration.
- Review the detected build output directory under deployment’s Advanced settings; correct it when detection was wrong.
- Deploy again after the build and destination agree, then test the public app.
Do not point the output at a directory containing secrets just to satisfy the check. A project may need a build correction rather than a different directory name.
