Regarding the configuration issues of the Claude code router.

How do the experts solve the issue of configuring the claude code router's config.json? I am using the openrouter API, but I encountered an API Error: 404 {"error":{"message":"Error from provider: {"error":{"message":"No endpoints found that support cache control","code":404}}}","type":"api_error","code":"provider_response_error"}}. Is this a problem with my configuration? I would appreciate any answers.
