Hi I’m writing an ndjson to upload assets with the cdf toolkit data plugin, I’m wondering how to format a double direct relation on the ndjson. This is the ndjson I’ve been working on… the first line I tried to represent the direct relation as a property but seems like it’s not it. I’m working with the ISA95 data model.

    Update there was a typo in the property name, however I got a different error now:

    Cannot ingest into a connection property

     

    Also realized the type of relation I want to represent is actually a multi_reverse_direct_relation

    Hey Gerardo,

     

    I hope all is well. It’s highly likely you’re getting the 

    Cannot ingest into a connection property error because you have a property defined as an edge. This will fail when an node upsert happens. Edges have a much higher survival rate when they’re on the “edge” or outside of a payload.

     

     

    So if I had to guess, I would say it’s a good chance it’s your property with the area_id: Compressor_Demo_Geonosis_Central-Utilities
