Reviewer not found:

Error message

Reviewer not found: 

What it means

OneDev's AI TOD (pull-request creation/edit) endpoint resolves each name in the 'reviewers' array via userService.findByName(). If a name does not match any existing user, it throws a JAX-RS NotFoundException (HTTP 404) with the offending name appended. The whole request aborts before any review objects are created.

Solutions

1. Verify each name in the 'reviewers' list matches an existing OneDev user login name exactly (check admin > user list).
2. Remove or correct the non-existent reviewer names and resubmit the request.
3. Pre-resolve names via the user API before submitting to filter invalid ones.

Example fix

// before
data.put("reviewers", List.of("Alice Smith"));
// after
data.put("reviewers", List.of("asmith")); // exact login name

for (var name : (List<String>) data.getOrDefault("reviewers", List.of())) {
    if (userService.findByName(name) == null)
        throw new IllegalArgumentException("Unknown reviewer: " + name);
}

try {
    callEditEndpoint(data);
} catch (NotFoundException e) {
    if (e.getMessage().startsWith("Reviewer not found")) {
        // strip the bad name from data.get("reviewers") and retry
    } else throw e;
}

When it happens

Trigger: POST to the TodResource pull-request edit endpoint with data containing a 'reviewers' list where any entry is not an exact existing username (e.g. reviewers=["alice","bob123"] when no user 'bob123' exists).

Common situations: Typo in reviewer name; AI agent hallucinating a username; reviewer was renamed or deleted since the plan was generated; using email/display name instead of login name.
