Hi, I'm really struggling to make an integration between AWS API Gateway and EventBridge, but I keep getting

API Gateway Integration: BadRequestException: Invalid ARN specified in the request

. Can anyone help me understand what am I doing wrong? This is the code:

const eventsResourcePOSTMethodIntegration = new aws.apigateway.Integration(
  "eventsResourcePOSTMethodIntegration",
  {
    restApi: restApi,
    resourceId: eventsResource.id,
    httpMethod: eventsResourcePOSTMethod.httpMethod,
    type: "AWS",
    credentials: apiGatewayRole.arn,
    passthroughBehavior: "NEVER",
    requestParameters: {
      "integration.request.header.X-Amz-Target": "'AWSEvents.PutEvents'",
      "integration.request.header.Content-Type": "'application/x-amz-json-1.1'"
    },
    uri: `arn:aws:apigateway:${region}:events:action/PutEvents`,
    integrationHttpMethod: "POST",
    requestTemplates: {
      "application/json": `#set($inputRoot = $input.path('$'))
      {
        "Entries": [
          #foreach($item in $inputRoot)
          {
            "Detail": $input.json("$[$foreach.index]"),
            "DetailType": "$item.eventType",
            "EventBusName": "test",
            "Source": "wrike.apigateway"
          }#if($foreach.hasNext),#end
        ]
      }
      #end`
    }
  },
  {
    dependsOn: [
      restApi,
      eventsResource,
      eventsResourcePOSTMethod,
      apiGatewayRole
    ]
  }
);

Do you think it might be the

uri

property? Where is

${region}

coming from?

Hi, It's comming from

const region = config.get("aws:region");

We have a couple of examples of API Gateway-EventBridge integrations in our examples repository that you might find helpful for reference — one using API Gateway v1 and the other with Gateway v2: • https://github.com/pulumi/examples/tree/master/aws-ts-apigateway-eventbridge • https://github.com/pulumi/examples/tree/master/aws-ts-apigatewayv2-eventbridge

I'll check that, but shouldn't

pulumi up

fail on other resources that use

region

too?

The provider itself (

@pulumi/aws

) will generally read that value correctly, whether from your stack config file or from your shell environment, so your deployment will generally be fine. But if you want to use that value within your program code as well, you need to read it by passing the “namespace” (in this case

aws

) to a new Config instance and reading the

region

setting with that instance.

Oh god... 4 hours on this. Chenged from

config.get

to

config.requeir

and

pulumi up

failed... thank you very much for the help

Ah, great! So it hadn’t been set at all, looks like.

Ok, I think I`ll advance on this now, always hard at the beginning. I`ll read the resources and try to get it done. Thanks again

You bet! Best of luck.
