Fix extension install error message showing raw struct instead of owner/repo by Copilot · Pull Request #12836 · cli/cli

Copilot · 2026-03-04T16:24:16Z

When an extension has no usable release artifact or script, the error message printed the raw Go struct representation (&{github gh-review-lab }) instead of the formatted owner/repo name.

Changes

pkg/cmd/extension/manager.go: Replace bare repo with ghrepo.FullName(repo) in the "not installable" error message
pkg/cmd/extension/manager_test.go: Add TestManager_Install_not_installable to assert the error message uses the owner/repo format

Before:

extension is not installable: no usable release artifact or script found in &{github gh-review-lab }

After:

extension is not installable: no usable release artifact or script found in github/gh-review-lab

Original prompt

When installing the gh-review-lab extension using gh extension install github/gh-review-lab, an error message is shown: extension is not installable: no usable release artifact or script found in &{github gh-review-lab http://github.com|github.com}. The final string in the error (&{github gh-review-lab <http://github.com|github.com>}) appears to be a formatting artifact, possibly due to improper handling of Go formatting or HTML escaping.

Task:

Investigate the code path that surfaces this error, particularly how the extension repository object is rendered in the error message.

Remove or properly format the artifact so that the error message clearly shows the intended repository name/link.

Ensure there are no HTML escapes (such as &) and that repository details are clearly presented.

Add a test or example that demonstrates the correct behavior.

Pull request overview

This PR fixes a bug where the extension "not installable" error message displayed the raw Go struct representation of a repository object (e.g., &{github gh-review-lab }) instead of the human-readable owner/repo format.

Changes:

Fix the %s format verb in the error string by replacing the bare repo argument with ghrepo.FullName(repo), which serializes to "OWNER/REPO".
Add TestManager_Install_not_installable to assert the corrected error format.

`pkg/cmd/extension/manager.go`	Uses `ghrepo.FullName(repo)` in the "not installable" error message instead of the raw `repo` struct

This MR contains the following updates: | Package | Update | Change | |---|---|---| | [cli/cli](https://github.com/cli/cli) | minor | `v2.87.3` → `v2.88.1` | MR created with the help of [el-capitano/tools/renovate-bot](https://gitlab.com/el-capitano/tools/renovate-bot). **Proposed changes to behavior should be submitted there as MRs.** --- ### Release Notes <details> <summary>cli/cli (cli/cli)</summary> ### [`v2.88.1`](https://github.com/cli/cli/releases/tag/v2.88.1): GitHub CLI 2.88.1 [Compare Source](cli/cli@v2.88.0...v2.88.1) #### Fix `pr` commands failing with `read:project` scope error v2.88.0 introduced a regression where `pr` commands would fail with the error: ``` error: your authentication token is missing required scopes [read:project] To request it, run: gh auth refresh -s read:project ``` Previously, missing read:project scope was gracefully handled, and project data was silently skipped. A change inadvertently broke the error matching that enabled this graceful degradation. v2.88.1 reverts these changes so that `pr` commands work correctly without requiring the `read:project` scope. #### What's Changed - Migrate Windows code signing from client secret to OIDC by [@BagToad](https://github.com/BagToad) in [#12911](cli/cli#12911) - Revert "refactor: deduplicate scope error handling between api/client.go and project queries" by [@williammartin](https://github.com/williammartin) in [#12914](cli/cli#12914) - Revert "fix: clarify scope error while creating issues for projects" by [@williammartin](https://github.com/williammartin) in [#12915](cli/cli#12915) **Full Changelog**: <cli/cli@v2.88.0...v2.88.1> ### [`v2.88.0`](https://github.com/cli/cli/releases/tag/v2.88.0): GitHub CLI 2.88.0 [Compare Source](cli/cli@v2.87.3...v2.88.0) ####
