File path is required

Error message

File path is required

What it means

renderer:show-in-folder requires a truthy filePath before delegating to Electron's shell.showItemInFolder. Thrown on empty string, null, or undefined so the native call is never invoked with an invalid path.

Solutions

1. Pass a non-empty absolute file path.
2. Disable the 'Show in folder' UI action when the selected item has no pathname.

if (!filePath || typeof filePath !== 'string') {
  throw new Error('filePath is required to reveal in folder');
}

/** @param {unknown} p @returns {p is string} */
function isNonEmptyString(p) {
  return typeof p === 'string' && p.length > 0;
}

try {
  await ipcRenderer.invoke('renderer:show-in-folder', filePath);
} catch (err) {
  if (/File path is required/.test(err.message)) {
    // disable the UI action; no file to reveal
  } else {
    throw err;
  }
}

When it happens

Trigger: Calling renderer:show-in-folder with no filePath argument (empty/null/undefined).

Common situations: Renderer offers 'Reveal in Finder' on a virtual or unsaved request that has no on-disk file; event fired before a path was assigned.
