Map function with lambda in a list of Python dictionaries

Good night, I'm taking the data via API and turning it into one .JSON to write to a list:. Inside lsta info there is a list of dictionaries called custom_fields, so I used map with lambda function to get the values:

info = r.json()

gravar=[]
for infos in info['tickets']:
        gravar.append((infos['url'],
                    infos['id'],
                    infos['created_at'],
                    infos['status'],
                    infos['requester_id'],
                    infos['collaborator_ids'],
                    infos['tags'],
                    map(lambda t: t["id"], infos['custom_fields']),
                    map(lambda v: v["values"], infos['custom_fields'])
    )) 

print(gravar[0])

Instead of returning the values, it is returning this way:

...<map object at 0x000001B3B27CEFD0>, <map object at 0x000001B3B27F0048>)

How do I list the elements within the dictionaries of that list?
