I have been looking around and facing an issue that I don’t see how to solve
I have the following query with rather simple data

SELECT distinct jsonb_build_object('entity', (select json_agg(t) 
from (
    select jsonb_build_object(
        'active',false
        ,'descriptionPersonne', (select  jsonb_build_object('a','a'))
        ) as personne
    union 
    select jsonb_build_object(
        'active',false
        ,'descriptionCompany', (select  jsonb_build_object('a','a'))
        ) as company
    )t)
    )   

my results look like this

{"entity": [
{"**personne**": {"descriptionCompany": {"a": "a"}, "active": false}}, 
{"personne": {"descriptionPersonne": {"a": "a"}, "active": false}}
]}

I don’t get why my first results is a personne and not a company

I have tried many other options like having a with statement, or json_build_array
