Error message

Pull request does not belong to specified project

What it means

OneDev throws this 406 NotAcceptableException when the referenced pull request exists but belongs to a project different from the project specified in the workspace creation request. Workspaces may only link pull requests from the same project.

Solutions

1. Check request.getProject() equals the PR's target project before calling; use a PR belonging to the specified project.
2. Change the request's projectId to the project the PR belongs to.
3. Omit pullRequestId if the linkage is optional for the workflow.

Example fix

// before
PullRequest pr = pullRequestService.get(data.getPullRequestId());
workspaceService.create(user, fork, issue, pr, ...);
// after
PullRequest pr = pullRequestService.get(data.getPullRequestId());
if (pr != null && pr.getProject().equals(project)) {
    workspaceService.create(user, project, issue, pr, ...);
}

PullRequest pr = pullRequestService.get(data.getPullRequestId());
if (pr != null && !pr.getProject().equals(project))
    throw new IllegalArgumentException("PR #" + pr.getNumber() + " belongs to " + pr.getProject().getPath());

boolean pullRequestInProject(PullRequest pr, Project project) {
    return pr != null && pr.getProject().equals(project);
}

When it happens

Trigger: POSTing to the workspace REST resource with project=X but pullRequestId referencing a PR in project Y (including PRs on forks whose target is a different project).

Common situations: Cross-repo automation pipelines passing a PR id from an upstream project; users confusing a fork's PR with the target project's PR; batch scripts that look up PRs globally.
