Question

Hi there! I have an issue understanding how to use https://docs.airbyte.com/connector-development/config-based/advanced-topics#parameters|$parameters from a parent to children stream.

  1. My parent stream look like this: /users/{{ stream_partition.user_id }}/posts and will return entities with post_id as primary key
    a. My child stream look like this: /users/{{ parameters.user_id }}/posts/{{ stream_partition.post_id }}/comments
    How should I build my parent and children yamls to support this kind of thing?

Ok I found a solution looking at the error providing me the available context…

  1. My parent stream look like this: /users/{{ stream_partition.user_id }}/posts
    a. My child stream looks like this: /users/{{ stream_partition.parent_slice.user_id }}/posts/{{ stream_partition.post_id }}/comments

No need for $parameters
