Kling AI Common Errors

Overview

Comprehensive guide to identifying, diagnosing, and resolving common Kling AI API errors during video generation.

Prerequisites

• Kling AI integration experiencing errors
• Access to request/response logs
• API key configured

Instructions

1. Identify the HTTP status code from the error response
2. Match the error code to the reference table below
3. Review the specific causes for your error
4. Apply the recommended solution
5. Test with a simple request to verify the fix
6. Add proper error handling to prevent recurrence

Output

• Diagnostic report identifying error type and root cause
• Code fixes with corrected authentication or retry logic
• Verified resolution through successful API test
• Enhanced error handling patterns integrated into codebase

Error Handling

Error Code	Cause	Solution
401 Unauthorized	Invalid/missing API key	Verify key, check Bearer format
400 Bad Request	Invalid parameters	Validate all required fields
403 Forbidden	Account/content issue	Check account status, review prompt
429 Rate Limited	Too many requests	Implement exponential backoff
402 Payment Required	Insufficient credits	Check balance, add credits
500/502/503 Server	Service outage	Wait and retry with backoff
Generation Failed	Complex prompt/timeout	Simplify prompt, reduce duration

Examples

Example: Diagnose Authentication Error Request: "My Kling AI video generation keeps failing with 401 errors" Result: Identified missing Bearer prefix in Authorization header, applied fix, verified with successful test generation

Example: Handle Rate Limiting Request: "Getting too many requests errors when batch processing videos" Result: Implemented exponential backoff retry decorator, added request queuing, batch processes without rate limit errors

Example: Debug Generation Failure Request: "Video generation fails with no clear error message" Result: Analyzed job details, identified prompt complexity issue, simplified scene description, successful on retry
