openclaw-config-fix

OpenClaw returns HTTP 500 errors because ${env:VAR} syntax in openclaw.json is misinterpreted as Java named capturing groups. Replacing these environment variable references with concrete values resolves the config parsing failure.

To fix Java regex errors, back up your openclaw.json, replace problematic ${env:...} references with actual values, verify JSON validity, and restart the gateway to ensure the configuration parsing failure is resolved.

The best way to remediate ${env:} syntax errors is to follow a documented workflow: back up the config, replace environment references with concrete values, validate the JSON structure, and restart the gateway for safe recovery.

Yes, you need to restart the OpenClaw gateway after replacing environment variable references in openclaw.json. Restarting the gateway ensures the configuration changes are applied and validates the remediation workflow.

Yes, you can automate the replacement of environment variable syntax in OpenClaw config files. The remediation process detects problematic ${env:...} references and prompts for replacement or performs automated fixes to prevent reoccurrence.

If OpenClaw config parsing fails after replacing ${env:} syntax, restore the backed up configuration file to revert changes. Ensure the substituted concrete values produce valid JSON before attempting another gateway restart.
