Error: Not supported when trying to connect with wrong username #151

i have the following users setup in my mysql db

select * from mysql.user;
+-----------+------------------
| Host      | User             
+-----------+------------------
| localhost | debian-sys-maint 
| localhost | mysql.infoschema 
| localhost | mysql.session    
| localhost | mysql.sys        
| localhost | root             
+-----------+------------------

when i now try to connect with a wrong non-existing user i get no error at all

const client = await new Client().connect({
  hostname: "127.0.0.1",
  username: "testuser",
  password: "Test12342",
});

when i then try to execute a sql query i get the following uninformative error message:

await client.execute(`CREATE DATABASE IF NOT EXISTS enok`);
error: Uncaught (in promise) Error: Not supported
      throw new Error("Not supported");

i would expect the following message

error: Uncaught (in promise) Error: Access denied for user 'testuser'@'localhost' (using password: YES)

i found out that this happens only for the strings 'testuser*' and 'root*', so for example username 'a_root' would give the correct error, or username 'a_testuser'
