Help with errors

General

I usually run Node-Red (3.1.6) (Node.js 20.11.1) as a service in Windows and so don't see the startup log. Today I had occasion to run from the command line and saw the following;

Unhandled rejection Error: No sockets available, cannot start.

Any help in resolving these gratefully accepted.

node-red-contrib-amazon-echo-aller is your issue - a node that does not correctly handle its errors.

It seems node-red-contrib-amazon-echo-aller has not been updated in 3 years, 8 months and the github repository shows it to be a fork of an even older node.

Normally, I would recomend that you contact the author by the repository issues page but that repository has issues disabled.

You may wish to change to one of the more up-to-date alexa nodes (I dont use alexa/amazon products, so cannot recommend any)

In the mean time, you can start node-red on the command line with the --safe flag

Thank you. I removed [node-red-contrib-amazon-echo-aller] and the errors have gone. I owe you a coffee :slight_smile:
