Hey @StainlessSteele This is in our backlog and we need to work with a dependency team before we could update support for Node.js 20. Sorry for the inconvenience and we will keep you posted on the updates.

this is causing problems because I can't use node 20 for creating office add ins. Any chance this gets pushed forward anytime soon?

All Teams bots and message extensions are built using the botbuilder-js SDK. We're currently waiting support for Node.js 20 in the Bot Builder SDK.
Related issue: microsoft/botbuilder-js#4550

Additionally, if you develop with Node.js 20 for the Teams template and samples, you'll encounter warnings but your development won't be blocked.
