How to solve "jq: error (at <stdin>:0): Cannot index number with string "description""

I use following script to get the description of a group in GitLab.

Script:

#! /bin/bash


GIT_API="https://git.xxxxxxxxxx.lk/api/v4"
GIT_TOKEN="xxxxxxxxxxxx"

curl -sS --request GET --header "PRIVATE-TOKEN: $GIT_TOKEN" "$GIT_API/groups/1079" | jq -r ".[] .description"

But it outputs following error:

jq: error (at <stdin>:0): Cannot index number with string "description"

How to solve this problem.

curl output:

{
  "id": 1079,
  "web_url": "https://git.xxxxxxxxxx.lk/groups/testdevops",
  "name": "testdevops20",
  "path": "testdevops",
  "description": "Test_1",
  "visibility": "private",
  "share_with_group_lock": false,
  "require_two_factor_authentication": false,
  "two_factor_grace_period": 48,
  "project_creation_level": "developer",
  "auto_devops_enabled": null,
  "subgroup_creation_level": "maintainer",
  "emails_disabled": null,
  "mentions_disabled": null,
  "lfs_enabled": true,
  "default_branch_protection": 1,
  "avatar_url": null,
  "request_access_enabled": true,
  "full_name": "testdevops20",
  "full_path": "testdevops",
  "created_at": "2021-05-31T04:56:28.467Z",
  "parent_id": null,
  "shared_with_groups": [],
  "runners_token": "Dw_LPVsbeChD6s6n1wRy",
  "projects": []
}

Solution

Fix the script as follow:

#! /bin/bash


GIT_API="https://git.xxxxxxxxxx.lk/api/v4"
GIT_TOKEN="xxxxxxxxxxxx"

curl -sS --request GET --header "PRIVATE-TOKEN: $GIT_TOKEN" "$GIT_API/groups/1079" | jq -r ".description"

The jq command works if written as jq -r ".description".
