claude-code - 💡(How to fix) Fix Claude Desktop: repeated 404 on /api/model_configs/claude-opus-4-6[1m] [1 participants]

2026-04-08 05:12:35 [error] [REACT_QUERY_CLIENT] QueryClient error: { "type": "not_found_error", "statusCode": 404, "endpoint": "/api/organizations/f9df3f20-xxxx/model_configs/claude-opus-4-6[1m]", "method": "GET", "message": "Not found" }

TL;DR

Remove the [1m] suffix from the model ID before making the API request to /api/organizations/{org_id}/model_configs/{model_id}.

Guidance

• Verify that the model ID is correctly formatted before the API call by checking the code that appends the [1m] suffix and ensure it is removed or not appended in the first place.
• Inspect the API documentation to confirm the expected format of the model ID in the model_configs endpoint.
• Consider adding input validation or sanitization to prevent similar issues with malformed model IDs in the future.
• Review the React Query client configuration to understand the retry loop behavior and consider adjusting it to prevent excessive requests.

Example

// Example of removing the suffix from the model ID
const modelId = 'claude-opus-4-6[1m]';
const cleanedModelId = modelId.replace(/\[.*\]/, '');
console.log(cleanedModelId); // Output: "claude-opus-4-6"

Notes

The provided information suggests that the issue is specific to the Claude Desktop application and its interaction with the API. The solution may need to be adapted based on the actual implementation details of the application.
