Sometimes a single message is split into two

[Tutorialwork]

protobuf.js version: 7.2.5

I have the problem that sometimes the same object with the same code is split into two messages and then it fails because this splitting is happening.
I use on the other side Java. I'm not sure if from which side the error is caused.

socket.write(RequestObject.encodeDelimited(requst).finish());
socket.on('data', (data: Buffer) => {
    try {
        const product: Product = Product.decodeDelimited(data);
        console.log(product);
    } catch (error) {
        let completeHexString = "";
        for (let i = 0; i < data.length; i++) {
            const hexString = data[i].toString(16).padStart(2, '0');
            completeHexString += `${hexString  } `;
        }
        console.log(completeHexString);

        logger.log('warn', `Error while decoding Product: ${error.message}`);
    }
});
