Running serverless package causes an output of cloudformation template with invalid zip content.

{
  "WsgiLambdaFunction": {
    "Type": "AWS::Lambda::Function",
    "Properties": {
      "Code": {
        "S3Bucket": "ops.orcahub-dev.com",
        "S3Key": "serverless/django-admin-hub/at-ut/1578920651517-2020-01-13T13:04:11.517Z/run_trigger.zip"
      }
    }
  },
  "RunUnderscoretriggerLambdaFunction": {
    "Type": "AWS::Lambda::Function",
    "Properties": {
      "Code": {
        "S3Bucket": "ops.orcahub-dev.com",
        "S3Key": "serverless/django-admin-hub/at-ut/1578920651517-2020-01-13T13:04:11.517Z/run_trigger.zip"
      }
    }
  }
}

Where in the correct case, S3Key should be different for each Function. This problem may or may not had caused provisioned concurrency to fail to deploy alias.

@jeffjen thanks for report. Can you minimize the test case, so it doesn't involve any plugins.

This problem may or may not had caused provisioned concurrency to fail to deploy alias.

sls package doesn't involve any deployment, and doesn't confirm anything on AWS side, so I take it's not related to it.
