Sequelize connection error

Question

I'm trying to transfer my application to a new machine. It works on the old machine perfectly, and I have been trying to copy the settings as closely as possible, but there is something missing. This is the error I'm getting:

Unhandled rejection SequelizeConnectionError: Handshake inactivity timeout
    at Handshake._callback (/Applications/MAMP/htdocs/dashboard-server/node_modules/sequelize/lib/dialects/mysql/connection-manager.js:63:20)
    at Handshake.Sequence.end (/Applications/MAMP/htdocs/dashboard-server/node_modules/mysql/lib/protocol/sequences/Sequence.js:96:24)

    at process._tickCallback (node.js:346:13)

Thoughts?

Answer 1

Just confirmed the problem is either Sequelize / mysql in conjunction with Node 4.2.0 after manually re-installing 4.1.1 my problems went away.

Downgrade to Node 4.1.x or wait for a patch/fix/etc to solve your issues.

Additional Information

The bug has been reported here on the node-mysql repository issue tracker. Seems someone regressed something in Node 4.2.0 and it wasn't caught. Here's the pull request to fix it which was merged in and is in the candidate for 4.2.1.

Update Oct 13th, 2015

Node 4.2.1 was just released (Changelog) containing the aforementioned fix. Upgrading to 4.2.1 should also fix your problems.
