Runtime failed to start: fork/exec /var/task/bootstrap: exec format error <nil>

[kdnakt]

Describe the bug
I created a maven project according to this guide:
https://github.com/quarkusio/quarkus/blob/master/docs/src/main/asciidoc/amazon-lambda.adoc

And got an error when I tried bash ./invoke-native.sh

Expected behavior
out file is like following when I created the function with invoke.sh.

{"result":"hello Bill","requestId":"1434f808-f8c4-4d8c-a507-fe4464273e6e"}

Actual behavior
out file is:

{"errorType":"Runtime.ExitError","errorMessage":"RequestId: 6b8192ad-5a30-4efa-a3e1-2905cfe5542e Error: &{0xc000092240 map[invoke_id:6b8192ad-5a30-4efa-a3e1-2905cfe5542e sandbox_id:0] 2019-11-08 17:40:39.511112521 +0000 UTC m=+0.070780883 panic <nil> Runtime failed to start: fork/exec /var/task/bootstrap: exec format error <nil> }"}

To Reproduce
Steps to reproduce the behavior:

1. Prepare an IAM Role with basic lambda policy:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "logs:CreateLogGroup",
                "logs:CreateLogStream",
                "logs:PutLogEvents"
            ],
            "Resource": "*"
        }
    ]
}

2. Create a maven project with mvn archetype:generate -DarchetypeGroupId=io.quarkus -DarchetypeArtifactId=quarkus-amazon-lambda-archetype -DarchetypeVersion=1.0.0.CR1 and edit create-native.sh's IAM Role ARN.
3. Run mvn clean install -Dnative and bash ./create-native.sh
4. And then bash ./invoke-native.sh shows error

@kdnakt, Does it work if you use Java 8 instead of Java 11?

[goranopacic]

@jaikiran I have the same problem with Java 8:

Having looked around a bit, it looks like in this case, either or both of you are building this native image on MacOS and then running it on Linux VM perhaps?

Can one you try using this command to build the native image locally:

mvn clean install -Dnative -Dquarkus.native.container-build=true

This should generate the native image within a container and you can then use the create-native.sh and invoke-native.sh as usual to try out the AWS function.

More details on generating a native-build through a container can be found here https://quarkus.io/guides/maven-tooling#build-a-container-friendly-executable

thanks @jaikiran - it works now!

[jaikiran]

@goranopacic Thank you for confirming. I'll close this now.

[kdnakt]

@jaikiran Thanks for your advice, I just confirmed it worked with Java11 following your advice!

Also, thank you for @goranopacic trying with Java8.
