@amaster.ai/function-client

Function invocation client for AMaster edge functions.

import { createFunctionClient } from "@amaster.ai/function-client";

const client = createFunctionClient();
const result = await client.invoke<{ ok: boolean }>("sendEmail", {
  to: "[email protected]",
});

if (result.error) {
  console.error(result.error.message, result.invocationId);
}

if (result.data) {
  console.log(result.data.ok);
}

Invocation Metadata

invoke() returns the normal ClientResult fields plus edge runtime metadata:

| Field | Source header | Description | | ----------------- | ---------------------------- | ------------------------------------------------------------------ | | invocationId | X-AMaster-Invocation-Id | Unique id for this function call. Use it to query invocation logs. | | functionVersion | X-AMaster-Function-Version | Function version selected by the runtime for this call. |

When a function behaves unexpectedly, keep result.invocationId with the observed response and query the OpenTelemetry runtime logs by that exact id. In agent-assisted debugging, use the Scheduler MCP runtime log search tool with invocation_id:

{
  "invocation_id": "inv_xxx",
  "limit": 20
}

For direct HTTP diagnostics, query the Scheduler logs API:

curl "http://localhost:8080/api/v1/logs/search?invocation_id=${invocationId}&limit=20"
