PDOException when querying with asterisk

Script to reproduce:

import requests

import json




base_url = "https://play.asti.ga/rest/"

username = "user@example"

password = "password"

client_name = "my_client"

version = "1.16.0"




token = password.encode('utf-8').hex()




params = {

    'u': username,

    'p': f"enc:{token}",

    'v': version,

    'c': client_name,

    'f': 'json',

    'query': '*',

    'songCount': '10',

}




response = requests.get(f"{base_url}search3", params=params)

print(response.text)

I got the following response:

getSubsonicId failed.PDOException: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1 in /var/www/astiga/play/app/Database.php:1718

I tried several queries:

• 'a*' => Same error
• 'aa*' => Worked
• 'aaa*' => Worked
• '\*' => Same error
• '\\*' => Same error
• 'あ*' => Worked

What's wrong with the query?
