ARK的GetApiKeyCommand发送出去返回404

[Enternalcode]

Deno.serve(async (req) => {
const logger = createLogger(req, 'volcengine-get-api-key');
try {
const { resourceIds, resourceType } = await req.json();
const arkClient = new ARKClient({
accessKeyId: accessKeyId,
secretAccessKey: secretAccessKey,
region: "cn-beijing",
});

const input = {
  DurationSeconds: Number(defaultStsTimeout),
  ResourceIds: resourceIds,
  ResourceType: resourceType,
  ProjectName: "tyt"
}

const resp = await arkClient.send(new GetApiKeyCommand(input));
const result = resp.Result;
logger.info(JSON.stringify(result))
if (result?.ApiKey && result?.ExpiredTime) {
  return new Response(
    JSON.stringify({
      apiKey: result.ApiKey,
      expiredTime: result.ExpiredTime
    }),
    { headers: { "Content-Type": "application/json" } },
  );
} else {
  throw new Error('Invalid response from Volcengine API: missing ApiKey or ExpiredTime');
}

} catch (err: unknown) {
const errorMessage = err instanceof Error ? err.message : 'Internal server error';
logger.error(Error in volcengine-get-api-key: ${errorMessage});
return new Response(
JSON.stringify({ error: errorMessage }),
{ status: 500, headers: { "Content-Type": "application/json" } },
);
}
});

根据文档复现的访问GetApiKey端口，但是一直返回404。
