Error in your pipeline. Step is empty, null or missing

[warmannj]

I have the following error when running my pipeline: 

Configuration error

There is an error in your bitbucket-pipelines.yml at [pipelines > branches > develop > 1]. To be precise: Step is empty, null, or missing.

Another user reported a similar issue earlier. The answer given there does not work for me as the issue was with indentation. My file does not have that error.

Here's my file: 

definitions:
  steps:
    - step: &deployToECS
      name: Deploy to ECS
      services:
        - docker
      script: # Modify the commands below to build your repository.
        - pipe: atlassian/aws-ecs-deploy:1.0.4
          variables:
            AWS_ACCESS_KEY_ID: $AWS_ACCESS_KEY_ID
            AWS_SECRET_ACCESS_KEY: $AWS_SECRET_ACCESS_KEY
            AWS_DEFAULT_REGION: $AWS_REGION
            CLUSTER_NAME: '$ECS_CLUSTER_NAME'
            SERVICE_NAME: '$ECS_SERVICE_NAME'
            TASK_DEFINITION: '$ECS_TASK_DEFINITION_FILE'
            DEBUG: 'true'
pipelines:
  branches:
    develop:
      - step: 
        <<: *deployToECS
        deployment: development

 PS: The question editor here removes spacing when I paste my file contents so indentation might not be correct here.

However, the pipeline works if I change the step to reuse the anchor inline:

pipelines:
  branches:
    develop:
      - step: *deployToECS
        deployment: development

This "works" but I can not override variables with the deployment specific variables in this case. 

Any suggestions would be helpful.

Same issue here. When using overrides the pipeline reports "Step is empty, null or missing"

@warmannj Solved it. It was a matter of indentation indeed.

Notice the extra indent inside - step:

pipelines:
  branches:
    develop:
      - step: 
          <<: *deployToECS
          deployment: development

Same for me.

Thanks you!

Thanks, that was that. It's incredible that Bitbucket Pipelines - Validator (atlassian.io) is so bad it doesn't catch absolutely any errors; Every time I reconfigure my pipeline mu spend around 10 commits till I get it right :/

I have the same problem anyone find a way to do this?  i have tried the <<: *deployToECS way it validates but then when pipelines build says its invalid...

[Matt Hudson]

Me too.
