No paper found with id "${id}". Confirm the forum/note id fr

Error message

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

What it means

The openreview paper command looks up a single note by its forum/note id. When the OpenReview API returns no notes for /notes?id=<id>, the command throws EmptyResultError because no paper corresponds to that id. OpenReview returns 200 with an empty notes array for unknown ids rather than a 404, so this check is required.

Solutions

Re-copy the full forum id from the openreview.net URL (the 26-char string after /forum?id=)
Confirm the paper is publicly visible on openreview.net (not withdrawn/deleted)
Check whether the id belongs to API v2 notes (some venues require the v2 endpoint)
Fetch /notes?id=<id> directly in a browser/curl to inspect the raw response
If you only have the paper title, use the openreview search command to resolve the correct id

Defensive patterns

Strategy: try-catch

Validate before calling

if (typeof id !== 'string' || !/^[A-Za-z0-9_-]{10,}$/.test(id.trim())) {
    throw new Error(`Expected an OpenReview note id (long opaque token), got: ${id}`);
}

Type guard

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

Try / catch

try {
    const paper = await paperCommand({ id });
} catch (err) {
    if (err instanceof EmptyResultError) {
        console.error('Unknown forum id; re-copy from openreview.net or resolve via search.');
    } else {
        throw err;
    }
}

Prevention

Copy the full 26-char id from the /forum?id= URL parameter
Confirm the paper loads publicly on openreview.net
Resolve unknown titles via the search command to get valid ids
Watch for v1 vs v2 API id mismatches for newer venues

When it happens

Trigger: openreviewFetch('/notes?id=<id>') succeeds but json.notes is missing or empty — the id does not match any public note on openreview.net.

Common situations: Truncated or mistyped forum id (copied partially from a URL); id from OpenReview API v1 used against a v2-only note (or vice versa); note withdrawn/deleted; passing an email or title instead of the hex note id.

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.
