How to allow usage of non-fqdn for SolusVM 2 VPS with SolusVM 2 WHMCS Module?

Answer

1. Connect to WHMCS server via SSH
2. Open the file {WHMCS_ROOT}/modules/servers/solusvm2vps/lib/SolusAPI/Requests/ServerCreateRequestBuilder.php in a text editor.
   Replace {WHMCS_ROOT} with the actual path to WHMCS web root directory.
3. find the following block in the file:

   CONFIG_TEXT: if (!empty($this->domain)) {
               $request['name'] = $this->domain;
              $request['fqdns'] = [ $this->domain ];
           } else if ($domainConfig->isEnabled()) {
               $domain = $domainConfig->getDomainForName($name);
               $request['name'] = $domain;
              $request['fqdns'] = [ $domain ];

   And comment the lines that contain 'fqdns':

   CONFIG_TEXT: if (!empty($this->domain)) {
               $request['name'] = $this->domain;
             ## $request['fqdns'] = [ $this->domain ];
           } else if ($domainConfig->isEnabled()) {
               $domain = $domainConfig->getDomainForName($name);
               $request['name'] = $domain;
              ##$request['fqdns'] = [ $domain ];
