Hi @Harpreet Sangar. I have both the use cases (as discussed and solved individually above) combined in one collection. I need to refer two different collections from a single collection1, one field has multiple reference IDs (

string[]

) of collection2 and the other field has a single ID (

string

) to refer in some other collection3. I have created a mid collection code_links as we figured out. I get

"out_of": 0

in the response as I'd need to use

filter_by

to refer collection2 and should avoid using

filter_by

to refer collection3. Can you suggest a way to handle this?
