        "type": "OAuthException",
        "code": 100,
        "error_data": "{\"blame_field\":\"targeting\"}",
        "error_subcode": 1487756,
        "is_transient": false,
        "error_user_title": "Locations can't be used",
        "error_user_msg": "Some of your locations overlap. Try removing a location.",
        "fbtrace_id": "AApf6HmHZneXVFLD1U8BK-D"

}

steps to reproduce 1- create a campaign

   -F 'objective=OUTCOME_AWARENESS'\
   -F 'status=PAUSED' \

   -F "access_token=$ACCESS_TOKEN"

then, create an adset for this campaign

  -F 'name=My Ad Set' \
  -F 'campaign_id=6680088172618' \
  -F 'daily_budget=1000' \
  -F 'targeting={"geo_locations":{"countries":["US"],"cities":[{"key":2427178}]}}' \
  -F "access_token=$MY_META_ACCESS_TOKEN" \
-F "billing_event=IMPRESSIONS"

Answer 1

Assuming that city you are attempting to target is within the US, you have overlapping locations (and hence the error message is correct). If you're targeting the whole of the US, you should remove the city. If you want to just target the one city, remove US.
