Export path: ${filePath} is not an existing directory

Error message

Export path: ${filePath} is not an existing directory

What it means

Thrown by 'renderer:export-environment' after the absolute-path check passes but fs.existsSync(filePath) is false or isDirectory(filePath) is false. The handler will not write export files into a non-existent or file (non-directory) path.

Solutions

1. Re-pick the directory via the folder dialog immediately before export.
2. Validate with fs.statSync(p).isDirectory() on the renderer side through a stat IPC, or surface the error and prompt re-selection.
3. Confirm the volume/share is mounted before retrying.

Example fix

// before
await window.Ipc.invoke('renderer:export-environment', { environments, environmentType, filePath: staleDir });

// after
const { filePath } = await window.ipc.invoke('main:select-directory');
await window.Ipc.invoke('renderer:export-environment', { environments, environmentType, filePath });

const stat = await window.ipc.invoke('main:stat', filePath);
if (!stat || !stat.isDirectory()) {
  throw new Error(`'${filePath}' is not an existing directory`);
}

function isExistingDirectory(stat: { isDirectory: () => boolean } | null): boolean {
  return !!stat && typeof stat.isDirectory === 'function' && stat.isDirectory();
}

try {
  await window.Ipc.invoke('renderer:export-environment', payload);
} catch (e) {
  if (String(e?.message).includes('not an existing directory')) {
    payload.filePath = await pickFolder(); await window.Ipc.invoke('renderer:export-environment', payload);
  } else throw e;
}

When it happens

Trigger: Passing an absolute path to a file instead of a folder, a path on a removable/unmounted drive, a deleted/moved directory, or a network share that is no longer mounted.

Common situations: User deleted/moved the target folder after picking it, chose a file path in an open-dialog that returns a file, removable media ejected, or SMB/NFS share dropped.
