Add per-field tooltips in the resourceMapper parameter

Feature Requests

The idea is:

resourceMapper fields do not allow adding a description or tooltip that guides users on how to fill the field. Other fields allow that.

My use case:

I’m building the JSON2Video node and I use resourceMapper for dynamic template fields. These fields have (or can have) a description that now it can’t be used because there is no tooltip in the resourceMapper.

I think it would be beneficial to add this because:

User using nodes that use resourceMapper (there are many) may have guidance/help when filling the field.

Are you willing to work on this?

I posted a PR (feat(editor): Support per-field descriptions in the resourceMapper parameter by qcardona · Pull Request #35257 · n8n-io/n8n · GitHub) that does this. Feel free to test it.

Nice catch, this is a real gap. resourceMapper is used everywhere (Airtable, Postgres, Notion, your JSON2Video node) and not being able to add per-field guidance makes complex mappings harder to get right on the first try. Great that you went ahead and opened a PR instead of just filing the request, that’s the kind of contribution that actually moves things forward. Tagging this for visibility so a maintainer can review the implementation.
