claude-code - 💡(How to fix) Fix [Bug] Invalid environment config values cause runtime error instead of validation [1 participants]

wrong values in claude json config throws an error and stops the loop, nice to have would be an error message saying json schema validation failed - values need to be strings.

TL;DR

The issue is likely caused by incorrect configuration values in the env block, specifically non-string values, which should be corrected to strings.

Guidance

• Verify that all values in the env block are strings, as the error message suggests that H.toLowerCase is undefined, implying a type mismatch.
• Check the CLAUDE_CODE_DISABLE_ADAPTIVE_THINKING and MAX_THINKING_TOKENS values to ensure they are enclosed in quotes, making them strings.
• Consider adding JSON schema validation to handle incorrect config values and provide informative error messages.
• Review the code that processes the env block to ensure it handles non-string values correctly.

Example

"env": {
  "CLAUDE_CODE_DISABLE_ADAPTIVE_THINKING": "1",
  "MAX_THINKING_TOKENS": "150000"
}

Notes

The provided error message H.toLowerCase is not a function suggests a type-related issue, but without more context, it's difficult to pinpoint the exact cause. Ensuring all config values are strings is a safe and reasonable first step.

Recommendation

Apply workaround: Correct the config values to strings, as shown in the example, to prevent the error and allow for further debugging or addition of JSON schema validation.
