URL must follow /@<username>/video/<id> format

Error message

URL must follow /@<username>/video/<id> format

What it means

The URL must be the canonical /@<username>/video/<numeric-id> path. Share links (vm.tiktok.com/...), bare video IDs, and other tiktok.com paths are explicitly out of scope, so the pathname regex /\/^\/@([A-Za-z0-9._-]+)\/video\/(\d+)\/?$/ failing produces this ArgumentError.

Solutions

  1. Open the share link in a browser and copy the resolved canonical /@user/video/<id> URL
  2. Verify the path matches /@<username>/video/<numeric id> (note the @ prefix)
  3. Strip query strings is not required (they are allowed), but ensure the pathname itself is the canonical video path

Example fix

// before
parseTikTokVideoUrl('https://vm.tiktok.com/ZMabc123/')
// after
parseTikTokVideoUrl('https://www.tiktok.com/@user/video/1234567890')
Defensive patterns

Strategy: validation

Validate before calling

const u = new URL(value); if (!/^\/@[A-Za-z0-9._-]+\/video\/\d+\/?$/.test(u.pathname)) throw new Error('not a canonical /@user/video/<id> URL');

Type guard

const isCanonicalTikTokVideoUrl = (v) => { try { return /^\/@[A-Za-z0-9._-]+\/video\/\d+\/?$/.test(new URL(String(v)).pathname); } catch { return false; } };

Try / catch

try { parseTikTokVideoUrl(url); } catch (e) { if (/format/.test(e.message)) console.error('Resolve share links to /@user/video/<id> first'); else throw e; }

Prevention

When it happens

Trigger: Passing a valid https tiktok.com URL whose pathname is not /@user/video/<digits> — e.g. vm.tiktok.com/abc123 share links, /t/ links, photo posts (/photo/<id>), or a video ID with non-digit characters.

Common situations: Copying a share link from the mobile app; URL-encoding or trailing junk in the path; username containing characters outside [A-Za-z0-9._-]; passing a video ID instead of a full URL.
