Node.JS menu on a migrated subscription in Plesk doesn’t work: Call to a member function getPath() on null

Symptoms

• Unable to open Subscriptions > example.com > Node.JS for newly migrated domain:

  PLESK_ERROR: Server Error
  500
  Error
  Call to a member function getPath() on null

• Domain example.com has non-existent nodejs-handler-path:

  MYSQL_LIN: MariaDB [psa]> select val from dom_param where param=’ext-nodejs-handlerPath’ and dom_id=(select id from domains where name=’example.com’ limit 1);
  +—————————-+
  | val |
  +—————————-+
  | /opt/plesk/node/7/bin/node |
  +—————————-+

  # ls -l /opt/plesk/node/7/bin/node
  ls: cannot access /opt/plesk/node/7/bin/node: No such file or directory

Cause

This is a Plesk bug with the Node.JS extension #EXTNODEJS-122 which is going to be fixed in the future updates.

Resolution

As a workaround, re-install Node.js: go to Extensions > My Extensions > Node.js > More > Remove and install it again.

Alternatively, update the database:

1. Connect to the server via SSH

2. Login to the database

   # plesk db

3. Modify the nodejs-handler-path to /opt/plesk/node/8/bin/node:

   MYSQL_LIN: update dom_param set val=’/opt/plesk/node/8/bin/node’ where dom_id=(select id from domains where name=’example.com’ limit 1) and param=’ext-nodejs-handlerPath’;
