Say I have a sns topic with an onEvent handler…

Copy code

const AlarmEventSchema = z.object({
  AlarmName: z.string(),
  AWSAccountId: z.string(),
  NewStateValue: z.enum(['ALARM', 'OK']),
  NewStateReason: z.string(),
  StateChangeTime: z.string(),
  Region: z.string(),
  OldStateValue: z.enum(['ALARM', 'OK']),
  Trigger: z.object({
    MetricName: z.string(),
    Namespace: z.string(),
  }),
});

const alarmTopic = new aws.sns.Topic(`${name}-alarm-topic`, {}, { provider, parent: this });

alarmTopic.onEvent(
      `${name}-handle-event`,
      async (ev) => {
        const proms = ev.Records.map(async (record) => {
          const alarmEvent = AlarmEventSchema.parse(JSON.parse(record.Sns.Message));
        });
        await Promise.all(proms);
      },
      undefined,
      { provider, parent: this },
    )

If I try and create this, I get the following error.

Copy code

error: Error serializing '(ev) => __awaiter(this, void 0, void ...': slack-alerts.ts(57,51)

    '(ev) => __awaiter(this, void 0, void ...': slack-alerts.ts(57,51): captured
      variable 'AlarmEventSchema' which indirectly referenced
        function 'bound parse': which could not be serialized because
          it was a native code function.

    Function code:
      function () { [native code] }

I’ve seen this workaround, but it does not seem to work for me. Wrapping the schema in a function like suggested there results in the following error.

You probably need to move the Zod function into the handler
