debug lambda using private docker registry, --build-image

I’m struggling to start a debug session of a local lambda function. I’ve added a debug configuration and added the following launch config:

"launch": {
    "configurations": [
      {
        "type": "aws-sam",
        "request": "direct-invoke",
        "name": "lambdas:index.handler (nodejs14.x)",
        "invokeTarget": {
          "target": "code",
          "projectRoot": "${workspace}/lambdas",
          "lambdaHandler": "index.handler"
        },
        "lambda": {
          "runtime": "nodejs14.x",
          "payload": {"json": {
            "Records": [
              {
                "messageId": "19dd0b57-b21e-4ac1-bd88-01bbb068cb78",
                "receiptHandle": "MessageReceiptHandle",
                "body": "Hello from SQS!",
                "attributes": {
                  "ApproximateReceiveCount": "1",
                  "SentTimestamp": "1523232000000",
                  "SenderId": "123456789012",
                  "ApproximateFirstReceiveTimestamp": "1523232000001"
                },
                "messageAttributes": {},
                "md5OfBody": "{{{md5_of_body}}}",
                "eventSource": "aws:sqs",
                "eventSourceARN": "arn:aws:sqs:us-east-1:123456789012:MyQueue",
                "awsRegion": "us-east-1"
              }
            ]
          }},
          "environmentVariables": {
          }
        }
      }
    ]
  }

If I try and run the sam local invoke... manually I get an error when trying to build the docker image. I have a private docker registry that I’m required to use. Maybe I need to change the registry that sam cli is using?

Also, when I try to use the debug configuration it shows a successful build but then pops up with this window:

In the meantime it seems reasonable for the toolkit to add support for the -bi flag since we already support --use-container

Launch configs can specify sam.buildArguments:

"launch": {
    "configurations": [
      {
        "type": "aws-sam",
        ...
        "sam": {
          "buildArguments": [ "-bi", "..." ]
        }
      }
    ]
  }

I believe SAM CLI uses https://github.com/aws/aws-lambda-runtime-interface-emulator but my knowledge is very limited in this area. For more guidance, you’ll want to open an issue here: https://github.com/aws/aws-sam-cli/issues

@justinmk3’s comment works too.

Thanks. I’ll have to test this out and get back.
