Hello,
I am trying to insert a reference to a document inside s document in Firestore with no luck.
This is the input data:
And it is inserted as strings:
However, I’d need to insert them as references to other documents, like here:
Is there any way to do this?
I’m answering to myself 
Digging on the module code, I’ve seen that it is not possible to add data as referenceValue in the default Firestore module.
I’ve patched it for me, so I’d like to ask you what is the preferred way of contributing back with my fix.
Thank you,
Hi @Albuendi, welcome to the community 
Seems like you figured it out already. The basic process of creating a community node would be described here: Creating nodes - n8n Documentation. This is usually the fastest way of making a new node available to other users.
We also welcome PRs for improving existing nodes, though it might take us some time to get through them unfortunately. The dev guidelines would be available here: n8n/CONTRIBUTING.md at master · n8n-io/n8n · GitHub
Thank you so much!
Hey, would you share how did you fixed it?
I urgently need this feature
You did it? I have the same problem.
