An issue with the FTP user creation: Internal error Failed to load tree data.

Symptoms

• The following error is shown when attempting to create an additional FTP user via Plesk > Domains > example.com > Dashboard > FTP > click on a directory icon:

  PLESK_ERROR: Internal error
  Failed to load tree data.

• Enabling debug with SQL queries shows that Plesk attempts to use an ID of another domain in plesk panel logs (/var/log/sw-cp-server/error_log or %plesk_dir%admin\logs\php_error.log):

  CONFIG_TEXT: DEBUG [dbquery] [748] SQL: SELECT domains.* FROM domains WHERE (id = 191)
  DEBUG [dbquery] [748] END: 0.00014 sec
  DEBUG [dbquery] [749] SQL: SELECT domains.* FROM domains WHERE (id = 191)

• The ID of a domain in question is different:

  # plesk db "select id from domains where name='example.com';"
  130

  PS plesk db "select id from domains where name='example.com';"
  130
