Same here. I will do some digging on this, but would appreciate some pointers. I guess it has to do with Elastic updates on the system.

Same happen if i upgrade php version to 7.3.

i found some way to fix it

go to:

vendor/elasticsearch/elasticsearch/src/Elasticsearch/ClientBuilder.php

find below:

private function prependMissingScheme($host) {    
    if (!filter_var($host, FILTER_VALIDATE_URL, FILTER_FLAG_SCHEME_REQUIRED)) {       
        $host = 'http://' . $host;    
    }    
    return $host;
}

replace to

private function prependMissingScheme($host)
{
     
      if (empty(parse_url($host, PHP_URL_SCHEME))) { 
         $host = 'http://' . $host; 
     } 

     return $host;
}

In PHP 7.3, these two flags are deprecated because they are already implied (since PHP 5.6). The ideal fix is to remove these flags. See php.watch's post about filter_var() deprecation warnings.

So the ideal fix would be replacing the following block with the block followed by it.

private function prependMissingScheme($host) {    
    if (!filter_var($host, FILTER_VALIDATE_URL, FILTER_FLAG_SCHEME_REQUIRED)) {       
        $host = 'http://' . $host;    
    }    
    return $host;
}

replace with this:

private function prependMissingScheme($host) {    
    if (!filter_var($host, FILTER_VALIDATE_URL)) {       
        $host = 'http://' . $host;    
    }    
    return $host;
}
