Error while migrating aws opsworks stacks to aws systems manager

Question

Following the steps from this blog post https://aws.amazon.com/blogs/mt/migrate-your-aws-opsworks-stacks-to-aws-systems-manager/

The exporter script provided throws the error below:

Traceback (most recent call last):
  File "stack_exporter.py", line 276, in 
    main()
  File "stack_exporter.py", line 234, in main
    export_stack(context)
  File "stack_exporter.py", line 163, in export_stack
    create_cloudformation_template(context, template_parameters)
  File "/home/ubuntu/migration/cloudformation/cloudformation_template_generator.py", line 57, in create_cloudformation_template
    param.apply_parameter_to_template(stack_exporter_context, yaml_template)
  File "/home/ubuntu/migration/cloudformation/cloudformation_parameter.py", line 64, in apply_parameter_to_template
    self.value(template, stack_exporter_context)
  File "/home/ubuntu/migration/opsworks/lb_migrator.py", line 521, in append_target_group_and_listener

  File "/home/ubuntu/migration/opsworks/lb_migrator.py", line 373, in append_target_groups_to_cfn_template
    health_check_info = tg_healthcheck(listener, health_check)
  File "/home/ubuntu/migration/opsworks/lb_migrator.py", line 541, in tg_healthcheck
    health_check_path = '/' + health_check['Target'].split(':')[1].split('/', 1)[1]
IndexError: list index out of range

Has anyone ran into this or found a way to resolve this?

Thanks

Answer

I would suggest passing "None" in the command line parameter `--lb-type` and then migrate your load balancer separately.

There was a version "released" May 25, but apparently there has been at least 2 updates since then. Make sure you have downloaded the most recent version as well. The ETag on the most recent S3 object is `6f5ffc96a28499e9af3bb23f80200e31` and the VersionId is `U.9K6yB20qa_xqlPJUYIX5f_.w.RL74K` the Last Modified date is 2023-06-23.

My opinion of that exporter script: hastily written, not tested -- LOTS of bugs and will create multiple issues for you down the road. Use it as a template to look at, but don't actually use it. Take some time to realize what the script is attempting to create for you, and then do it the right way.

I've been documenting my progress on migrating on a Medium article
