I am following the docs

gh api \
  --method POST \
  -H "Accept: application/vnd.github+json" \
  -H "X-GitHub-Api-Version: 2022-11-28" \
  /repos/OWNER/REPO/issues \
  --input - <<< '{
  "title": "Issue title",
  "body": "Issue description.",
  "assignees": ["copilot-swe-agent[bot]"],
  "agent_assignment": {
    "target_repo": "OWNER/REPO",
    "base_branch": "main",
    "custom_instructions": "",
    "custom_agent": "",
    "model": ""
  }
}'

However, it fails

Creating issue with Copilot assignment via REST API...
Failed to create issue with Copilot assignment

    }
  ],
  "documentation_url": "https://docs.github.com/rest/issues/issues#create-an-issue",
  "status": "422"
}
Issue NOT created - Copilot assignment required

Is there a setting I needed to turn on to make it work?

I would recommend watching suggested actors using a GitHub GraphQL API query like this:
gh api graphql -f query='
query($owner:String!, $repo:String!) {
repository(owner:$owner, name:$repo) {
suggestedActors(capabilities:[CAN_BE_ASSIGNED], first:100) {
nodes {
__typename
login
... on Bot { id }
... on User { id }
}
}
}
}' -F owner='' -F repo=''

more details you can get using this link https://docs.github.com/en/copilot/how-tos/use-copilot-agents/coding-agent/create-a-pr

Issue: Wrong bot username

Your error shows "Copilot" and "github-actions[bot]" but your code has "copilot-swe-agent[bot]".

Fix:

1. Check available bots:

   gh api /repos/OWNER/REPO/assignees

2. Try without assignees - let agent_assignment handle it:

   {
     "title": "Issue title",
     "body": "Issue description.",
     "agent_assignment": {
       "target_repo": "OWNER/REPO",
       "base_branch": "main"
     }
   }

3. Verify prerequisites:

   • Copilot Enterprise/Workspace enabled
   • Bot has repo access

What's your GitHub plan? This feature requires specific Copilot tiers.

I resolved the issue. The default GITHUB_TOKEN doesn't have the permission to add the copilot bot as an assignee. I created a PAT token and that worked just fine.

Hi @mihirjoshi21
were you able to successfully assign a custom_agent within the agent_assignment object? If so, could you specify what the valid parameter or format is for that field?
Thanks
