OpenRouter discount routing skipped: ${formatError(error)}

Error message

OpenRouter discount routing skipped: ${formatError(error)}

What it means

Logged by the OpenRouter discount provider router plugin transform when routeOpenRouterRequestByEndpointDiscount throws while inspecting/rerouting a request. The transform deliberately degrades gracefully: it warns and returns undefined so the request proceeds unchanged through the gateway without discount routing.

Solutions

1. Inspect the formatted error; if it is a body-parse failure, restrict the router plugin to JSON chat-completion endpoints or disable it for other routes.
2. Update the plugin's endpoint discount configuration to match current OpenRouter catalog paths.
3. Upgrade the core package for fixes to the router's parsing logic.
4. As a stopgap, disable the openrouter-discount-provider-router plugin — requests route normally at list price.

Example fix

// plugin config: disable discount routing if it keeps failing
// before
{"plugins":["openrouter-discount-provider-router"]}
// after
{"plugins":[]}

When it happens

Trigger: An OpenRouter-bound request whose body cannot be parsed as expected (non-JSON body, unexpected model string), missing/invalid OpenRouter pricing metadata configured for the plugin, or a bug in the discount lookup for the specific endpoint being called.

Common situations: Client sends a streaming or non-JSON payload the router tries to read; OpenRouter changes endpoint path shapes; the plugin's discount config references endpoints that no longer exist.
