Unable to install WP instance with specific plugin/theme set: There is no custom asset by path

Symptoms

• Unable to install WP instance for the website with specific plugin/theme set:

  PLESK_ERROR: Could not install the set on the WordPress website.
  - Unable to install plugin 'plugin-name' with version '1.0.0' to 'WordPress installation #1 ('https://example.com')'. WP-CLI response: 'There is no custom asset by path '/usr/local/psa/var/modules/wp-toolkit/custom-asset/69db601b-c128-4e17-8726-31f9bad9262f/plugins/plugin-name/1.0.0/plugin-name.zip''

• The messages indicating that user's GUID was changed recently can be found in the Action Log:

  CONFIG_TEXT: 127.0.0.1 admin [2025-07-22 22:04:42.694] 'Update Client GUID' ('Client GUID': '69db601b-c128-4e17-8726-31f9bad9262f' => '69db601b-c128-4e17-8726-31f9bad9262f', 'Client Type': 'admin' => 'admin', 'Contact Name': 'Administrator' => 'Administrator', 'GUID': '4bf4a743-c1c2-4e08-bfa5-1262c83eb558' => '69db601b-c128-4e17-8726-31f9bad9262f', 'Login Name': 'admin' => 'admin')

Cause

There is a feature in Plesk that changes the server's GUID during a license key update if another server with the same GUID is already registered in the Key Administrator server database.

This change in GUID triggers updates in the WordPress Toolkit's sqlite3 database, but the subdirectory in custom-asset is not renamed accordingly. This issue has been reported under bug ID EXTWPTOOLK-13458.

Resolution

The workaround is to upload the plugin's zip file again:

Is it possible to deploy WordPress websites pre-configured with a custom theme and plugins in Plesk?
