Sequelize NodeJS server throwing "ERR_UNKNOWN_ENCODING" error

Question

could anyone help me locate the problem. I'm getting this error:

node:internal/streams/writable:296
       throw new ERR_UNKNOWN_ENCODING(encoding);
       ^

 TypeError [ERR_UNKNOWN_ENCODING]: Unknown encoding: <ref *1> Handshake {

     at readableAddChunk (node:internal/streams/readable:279:9) {
   code: 'ERR_UNKNOWN_ENCODING'
 }

I currently have no idea what's wrong. Figured out, that the problem lies here:

const sequelize = new Sequelize(process.env.DB_DATABASE, process.env.DB_USER, process.env.DB_PASSWORD, {
    host: process.env.DB_HOST,
    port: process.env.DB_PORT,
    dialect: 'mariadb',
});

sequelize.authenticate()
    .then(() => {
        logger.log('info', 'Connected to database')
    })
    .catch((error) => {
        logger.log('error', 'Failed to connect to database!');
        logger.log('error', JSON.stringify(error));
    })

in the authenticate function. Database: mariadb:10.5.7-focal (docker)

Everything worked before, because I used an older version of MariaDB, had to run npm update and the problem fixed itself.
