Errors when mapping owner id & select fields to pipedrive leads (but not person or org)

I’m mapping a website form to create a lead on Make.com.
I’m able to map integers to owner_id and text to select fields for both persons and organisations.

But I’m getting errors when I try to map the exact same fields for leads and I don’t know why.
For example, when I try to map the exact same owner_id for leads, I get this error: “error 400: provided dataset is not valid (“owner_id” must be a number)”. I’m stumped on this one. Mapping the variable = “12345” does not work. But typing down “12345” works.

When I map the same select field, I get this error “error. 400: provided dataset is not valid (Custom field validation failed. Error: Expected ‘number’ as value of singleOption field.”. (I get that this is asking for the ID of the select field item, but mapping text worked for persons and orgs, why not leads as well?
