This error message is indicating that the MySQL connection URL provided is not in the correct format. The correct format for a MySQL connection URL is:

mysql://[[user]:[password]@]host[:port][/database][?unix_socket=socket-path]

Here are the different components of the URL:

• mysql:// - This is the protocol used to connect to MySQL.
• [[user]:[password]@] - Optional. This specifies the username and password to use for authentication. If not provided, the connection will be made anonymously.
• host - This is the hostname or IP address of the MySQL server.
• [:port] - Optional. This specifies the port number to use for the connection. If not provided, the default port (3306) will be used.
• [/database] - Optional. This specifies the name of the database to connect to. If not provided, the connection will be made to the default database for the user.
• [?unix_socket=socket-path] - Optional. This specifies the path to the Unix socket to use for the connection. If not provided, a TCP/IP connection will be used.

Make sure that the URL you are providing follows this format. If you are still having issues, check that the username, password, hostname, and port number are correct and that the MySQL server is running.
