Troubleshooting

The Tessl CLI provides diagnostic capabilities through the tessl doctor command that outputs information about the environment and the CLI itself. This information can be helpful to support and in diagnosing issues. Additionally the CLI will provide guidance on how to resolve issues that are detected. The CLI output defaults to human readable output and can be configured to output JSON for reporting automation.

Usage

tessl doctor [--json]

Flags

  • --json (boolean, optional): Output diagnostics as JSON for programmatic processing

Examples
