TL;DR

The issue is likely caused by a null value being passed to a function that expects an object with an 'effortLevel' property, and a potential workaround is to check the input data or configuration.

Guidance

• The error messages indicate a TypeError caused by attempting to read the 'effortLevel' property of a null object, suggesting that the input data or configuration may be incorrect.
• Verify that the input data or configuration being passed to the hH0 function at cli.js:1845:3909 contains the expected 'effortLevel' property.
• Check the documentation or code for the hH0 function to determine the expected input format and ensure that it matches the data being passed.
• Consider adding error handling or input validation to prevent null values from being passed to the function.

Example

No code example is provided as the issue is related to a specific library and function, and without more context, it's difficult to provide a relevant example.

Notes

The issue may be specific to the @anthropic-ai/claude-code library and its version, and further investigation may be required to determine the root cause.

Recommendation

Apply a workaround by checking the input data or configuration to ensure it contains the expected 'effortLevel' property, as the root cause of the issue is likely related to incorrect input data.
