NOT_FOUND

Error message

File "${input.fileId}" not found.

What it means

Thrown by resolveAudio (called from transcribe) when input.fileId is set but FileModel.findById returns null. The FileModel is constructed userId-scoped, so findById only finds files owned by the caller — a file belonging to another user is indistinguishable from a non-existent one. This fires before any S3 access is attempted.

Solutions

1. Re-upload the audio file via the file upload endpoint and use the freshly returned fileId.
2. Verify the fileId was created under the same userId (and workspaceId, if applicable) as the transcribe call.
3. Check the file still exists via the file API before passing it to transcribe.
4. Ensure the audio was uploaded through the same environment (dev vs prod) as the transcription request.

Example fix

// before: stale or foreign fileId
await asr.transcribe({ fileId: 'old-or-wrong-id', model: 'whisper-1' }); // -> NOT_FOUND

// after: re-upload and use fresh id
const { id } = await uploadAudioFile(file);
await asr.transcribe({ fileId: id, model: 'whisper-1' });

// Verify the file exists and is owned by the caller before transcribing
const file = await fileRouter.getFile.query({ id: input.fileId });
if (!file) {
  throw new Error('File not found or not owned by caller; re-upload');
}
await asrRouter.transcribe.mutate(input);

const isExistingFile = (
  file: { id: string; userId: string } | null | undefined,
  userId: string
): file is { id: string; userId: string } =>
  !!file && file.userId === userId;

try {
  await asrRouter.transcribe.mutate(input);
} catch (e) {
  if (e.shape?.data?.code === 'NOT_FOUND' && /File.*not found/.test(e.message)) {
    // prompt re-upload
  } else throw e;
}

When it happens

Trigger: Calling transcribe with a fileId that does not exist in the files table, or exists but belongs to a different userId/workspace. The query at FileModel.findById(input.fileId) returns null because of the ownership scoping.

Common situations: Stale fileId from a deleted file. Cross-user/cross-workspace fileId leak. A typo or truncated id. File uploaded to a different workspace than the one the transcription call is scoped to.
