Any idea why am I getting typescript errors?

error TS2339: Property 'send' does not exist on type 'ECSClient'

when I run

pulumi preview

but everything is fine in IDE

import {ECSClient,ListServicesCommand} from "@aws-sdk/client-ecs";
import * as aws from "@pulumi/aws";
import * as pulumi from "@pulumi/pulumi";
const clusterName = "myCluster"
const myService = "myService"
const ecsClientPromise = aws.getRegion(undefined, { parent: this }).then((r) => new ECSClient({ region: r.name }))

const serviceArn = ecsClientPromise.then(async (ecsClient) => { 

  const listServicesOutput = await ecsClient.send(new ListServicesCommand({
    cluster: clusterName,
  }))

  const serviceArn = listServicesOutput.serviceArns?.find((f: string)=>f.match(new RegExp(myService, 'g')))
  return serviceArn
});
pulumi.all([serviceArn]).apply(console.log)

First, it would be good to paste those errors 🙂 But as I pasted this in my IDE I clearly see some missing imports marked as red (I'm actually using PHP Storm, so Jetbrains IDE family)

thanks for pointing it out,

nice, good catch

it was not fix sadly
