Hi @gauravmakkar, I think I have an idea. I believe you need to have a resolver for every item tagged with @client — but ppsConfiguration does not have a resolver — conversely, I believe you don’t need @client attached to things that are sub-properties of something else that is already @client (example: bin_group_details or pps_bin_details ).

[PCreations]

Even if you implement the correct resolvers, you will struggle with this issue #226 because there is actually a problem with how we deal with nested client queries.

Since this is directly related to #226 (which has PR #235 associated with it), I'll close this off. Let's continue the discussions in #226. Thanks!
