JSON.stringify(message) Error

[aaron-neal]

Hi, I am new to discord.js and this nod-red node. However, I am getting the following error when i receive a message. This crashes node-red and requires a restart.

It is related to circular structure in the discord.js message object, happens for channel and author too. Currently working by commenting out those bits.

I'm seeing this periodically on my own instance, as well, though whenever it happens for me it doesn't always crash node-red.

Originally, the idea was to expose the original discord.js data via a property of the node-red message, so that developers could essentially write all kinds of functionality without requiring specific code in node-red-contrib-discord, but it appears that this doesn't really work. I'll probably remove this functionality completely and see if there's still a strong use case for it.

Hi, I have the exact same pb any time I receive a message :(

Maybe you should surround the toJSON statement by a try catch.

Fixed in v3.0.0. Unfortunately, a lot of data is now removed (you can't retrieve a user's name anymore via msg.author.name) but I'll see if I can reïntroduce some of this data and provide a better API for sending messages to arbitrary Discord channels.

Addendum: v3.0.0 should be usable again for basic "reply" style bots, e.g. bots that reply to messages like "!help". Unfortunately, a lot of information about message authors and channel the message was received on is now only available in a rather obtuse way, which makes creating Node-red flows suboptimal. See #5 for the issue which attempts to reïntroduce this data properly.
