@Thinking80s Hello! I'm here to help you with bugs, questions, and becoming a contributor. While you wait for a human maintainer, I'm available to assist you.

It appears that you are encountering an issue where the length of the kb_content output variable must be less than 30 characters. Unfortunately, I couldn't find specific information about the kb_content variable in the repository. However, there are configuration files or settings that specify constraints or validation rules for variables in general.

For example, the checkValid function in the nodeDefault object contains validation rules for the KnowledgeRetrievalNodeType payload. This function checks for required fields and conditions based on retrieval_mode [1].

If you need to enforce a length constraint on kb_content, you might need to implement a similar validation check in your code. Here is a basic example of how you could add a length check:

function validateKbContent(kb_content: string): { isValid: boolean, errorMessage: string } {
    let errorMessage = '';
    if (kb_content.length >= 30) {
        errorMessage = 'The length of kb_content must be less than 30 characters';
    }
    return {
        isValid: errorMessage === '',
        errorMessage: errorMessage,
    };
}

You can integrate this function into your existing validation logic to ensure that kb_content meets the required length constraint.
