Notion one-way Relation property not found by n8n

Describe the problem/error/question

If a Notion Relation property is one-way, it is not found in Notion nodes (filters, add page, update page).
Once you add a backward relation, the property appears.

The bad news are that two-way relations are sometimes must be avoided as it may result in thousands of items slowing down DB.

This is the n8n part, using Notion filters. The Account property is visible ONLY if I enable the Show on toggle above.

Hey @artildo,

I have closed the GitHub issue to save on duplication, I suspect this is a property type that we don’t support so we would need to add support for it.

We have NODE-1494 open to look into adding this in the future.

@Jon Hi

Could you clarify meaning of “not supported”? This property type does exist in n8n Notion node. It’s just underdeveloped.

Hey @artildo,

My first thought was “I suspect this is a property type that we don’t support so we would need to add support for it.” not that it is “not supported”.

Normally if a field is not working it could be that we didn’t add support for the option or as you have called it, “underdeveloped”.

Once we get a chance to look at the dev ticket we will know more… Looks like it has a medium priority but it is still in the Triage queue so we won’t know until Wednesday morning if it it will be picked up quickly or moved to backlog for later.
