Unhandled exception with "import_path" in latest cloudformation-cli and go-plugin versions

[maastha]

When running make command for submitting certain resources, we recently started running into errors related to import_path.

These errors don't occur for older versions below: cloudformation-cli==0.2.33 cloudformation-cli-go-plugin==2.0.4

The issue occurs if the latest versions of the CLI are used i.e. cloudformation-cli v0.2.34 and v0.2.35 and cloudformation-cli-go-plugin v2.2.0

Also, note that we run into this only for certain resources. For reference below is rpdk-config for one such resource:

{
    "artifact_type": "RESOURCE",
    "typeName": "MongoDB::Atlas::NetworkContainer",
    "language": "go",
    "runtime": "go1.x",
    "entrypoint": "handler",
    "testEntrypoint": "handler",
    "settings": {
        "importpath": "github.com/mongodb/mongodbatlas-cloudformation-resources/network-container",
        "protocolVersion": "2.0.0",
        "pluginVersion": "2.0.4"
    }
}

➜  make
cfn generate

Because of this change: https://github.com/aws-cloudformation/cloudformation-cli-go-plugin/pull/168

You will need to adjust your settings appropriately:

"settings": {
        "import_path": "github.com/mongodb/mongodbatlas-cloudformation-resources/network-container",
        "protocolVersion": "2.0.0",
        "pluginVersion": "2.0.4"
    }
