Error message

No forum found with id "${forum}". Confirm the forum id from openreview.net.

What it means

The reviews command first fetches the root note of the forum (/notes?id=<forum>) to anchor the reply thread. If that query returns no notes, the forum id does not correspond to any public note, and EmptyResultError is thrown before fetching replies.

Solutions

1. Re-copy the forum id from the openreview.net paper URL (?id= parameter)
2. Confirm the paper loads publicly in a browser on openreview.net
3. Use the openreview search command to find the paper and get its correct id
4. Try the review-thread id only if it is the root forum id — replies are not valid forum ids

Example fix

// before
openreview reviews --forum WRONGID
// after (resolve id via search first)
openreview search "paper title"   # take the id column
openreview reviews --forum <id-from-search>

if (typeof forum !== 'string' || forum.trim().length < 10) {
    throw new Error(`Forum id looks invalid: ${forum}`);
}

function isLikelyForumId(v) {
    return typeof v === 'string' && v.trim().length >= 10 && /^[A-Za-z0-9_-]+$/.test(v.trim());
}

try {
    const reviews = await reviewsCommand({ forum });
} catch (err) {
    if (err instanceof EmptyResultError) {
        console.error('Forum not found; verify the root paper id on openreview.net.');
    } else {
        throw err;
    }
}

When it happens

Trigger: openreviewFetch('/notes?id=<forum>') succeeds but json.notes is empty — the given forum id matches no public OpenReview note.

Common situations: Mistyped or truncated forum id from a paper URL; paper withdrawn or restricted (not publicly visible); using a review/reply id instead of the forum (root paper) id; venue moved to OpenReview API v2 where ids differ.

Understand the failure class

Background: EmptyResultError / "no results found": when an API or scraper succeeds but returns zero rows — this error's family across 9 libraries.
