Issue while parsing JSON response using jq

curl -H "Authorization: token " -H "Accept: application/vnd.github.v3+json" "https://api.github.com/repos///pulls?state=closed&per_page=100&page=1" | jq -r '.[] | [.number, .created_at, .state, .user.login, .title, .base.ref, .head.ref, .html_url] | @csv' | tr -d '"'

jq: error (at :4): Cannot index string with string "number"

I should get the list of Pull requests, but throwing an error.
