Unable to find pull request #{0} in project {1}

Error message

Unable to find pull request #{0} in project {1}

What it means

PullRequestDetailPage looks up the pull request by number in the current project; when pullRequestService.find returns null it throws EntityNotFoundException with this message. The number was valid but no matching pull request exists in that project.

Solutions

1. Confirm the PR number exists in this project's pull requests list.
2. Check the URL's project path — the PR may belong to a different (e.g. fork) project.
3. Use the pull request list or search to obtain the correct link.

Example fix

// before
open("/projects/" + wrongProject + "/~pulls/" + number);
// after
open("/projects/" + request.getTargetProject().getPath() + "/~pulls/" + request.getNumber());

PullRequest request = pullRequestService.find(project, number);
if (request == null) throw new IllegalArgumentException("PR #" + number + " not found in " + project.getPath());

boolean prExistsInProject(Project p, long number) { return pullRequestService.find(p, number) != null; }

try { showPullRequest(number); } catch (EntityNotFoundException e) { renderPrMissing(number); }

When it happens

Trigger: Accessing a PR detail URL whose number does not exist in the project (deleted PR, wrong project, number beyond existing range).

Common situations: Following links from notifications after the PR was deleted; confusing a fork's PR numbers with the target project's numbers; database restored from an older backup while links were newer.

Understand the failure class
