GitHub Copilot Troubleshooting

Use this guide to resolve issues related to GitHub Copilot metrics, authorization failures, scope mismatches, and unexpected adoption behavior.

403 AiMetricsUnauthorizedException

Symptom

• Connection fails during setup
• No Copilot data appears in AI Insights
• 403 Unauthorized error

Root cause

• GitHub Copilot Usage Metrics policy is not enabled at the organization level.

Resolution

• Enable Copilot usage metrics in GitHub organization settings.
• Reauthorize the integration in LinearB.

No data after successful connection

Possible causes

• Initial backfill still processing (up to 90 days).
• Copilot is enabled but not actively used.
• Token lacks required scopes.

Resolution

• Wait for initial sync to complete.
• Verify PAT includes required scopes (user:read, read:org).
• Confirm Copilot usage metrics policy is enabled.

Adoption Rate above 100%

Symptom

• Adoption rate exceeds 100% in AI Insights.

Explanation

Copilot usage is measured at the GitHub organization level, while Git activity in LinearB may be scoped to a subset of repositories. If Copilot users exist outside the connected repository scope, the denominator (Git active users) may be smaller than Copilot active users.

Resolution

• Expand repository coverage in LinearB.
• Align GitHub organization selection with repository scope.

Missing organizations

Symptom

• Expected GitHub organizations do not appear during configuration.

Root cause

• The Personal Access Token does not have visibility into those organizations.

Resolution

• Regenerate the PAT with correct organization access.
• Confirm token owner has access to the target organizations.

User-level data missing

Organization-level Copilot data may appear even if individual users are not visible in the Users page.

Possible causes

• Copilot usage metrics policy not fully enabled.
• GitHub users not mapped to LinearB users.
• Token scope limitations.

Resolution

• Verify policy settings.
• Verify GitHub user mapping.
• Reauthorize if needed.

Reauthorization required

If the integration shows Disconnected:

• Generate a new PAT.
• Reauthorize in Settings → Company Settings → AI Tools → GitHub Copilot.
