ER_TRUNCATED_WRONG_VALUE: Incorrect datetime value

So i've recently completed an application for a study project. It's all good, and all I have left is putting the application to production.

I'm using MySQL with Node.js(I know, we don't like that, but someone's gotta try it). I have a socket that adds a chat message to the mysql Message Table, which contains the text, date time etc. The date time is set to new Date().

Now as I placed the application in a production server(reinstalling dependencies, mysql etc.), I suddenly get this error when I write messages:

Error: ER_TRUNCATED_WRONG_VALUE: Incorrect datetime value: '2017-06-01T09:45:06.253Z' for column 'message_datetime' at row 1

I did not get that error in development, so I asked myself if I downloaded different versions of mysql... and I did:

Development:

mysql  Ver 14.14 Distrib 5.5.54, for debian-linux-gnu (i686) using readline 6.3

Production

mysql Ver 14.14 Distrib 5.7.18, for Linux (x86_64) using EditLine wrapper

and the message table looks like this:

CREATE TABLE message ( message_id INT AUTO_INCREMENT, message_sender_id VARCHAR(80) NOT NULL, message_datetime DATETIME, message_text TEXT, message_chat_id INT NOT NULL, PRIMARY KEY(message_id), FOREIGN KEY(message_chat_id) REFERENCES chat(id) ON DELETE CASCADE ) ENGINE=InnoDB;

So what are the differences? Why is 'yyyy-mm-ddThh:mm:ss.%%%Z' suddenly not a valid date format? How do I fix this?

Thankful for any help!
