Error message

Missing file

What it means

parseAttachment throws 'Missing file' when running in web (non-desktop) mode but input.file is not provided. In the browser, file parsing uses an uploaded File object via parseUploadedAttachment (POST /api/v3/ai/chat/attachment/parse/upload with multipart formData). Without a File object, there is nothing to upload.

Solutions

1. Verify the File object is present before calling parseAttachment in web mode.
2. Handle the file-picker cancel case and avoid calling parseAttachment when no file is selected.
3. Use an assertion or early-return if input.file is falsy.

Example fix

// before
await parseAttachment({ file: selectedFile });

// after
if (!isDesktop && !selectedFile) {
  message.warning('Please select a file first');
  return;
}
await parseAttachment({ file: selectedFile });

if (!isDesktop && !(input.file instanceof File)) {
  message.warning('Please select a file to attach');
  return;
}

function isWebFileInput(input: { file?: File }): input is { file: File } {
  return !isDesktop && input.file instanceof File;
}

When it happens

Trigger: Calling parseAttachment({ filePath: '/some/path' }) or parseAttachment({}) while isDesktop is false. The caller passed a file path instead of a File object in browser context, or the file input returned null/undefined.

Common situations: A file picker that returned null (user cancelled). Code path designed for desktop that passes filePath but runs in browser. File object dropped during state propagation.
