if i change to 20, or 22, , I get a error
Unsupported Node.js version: v22.17.1. Please use Node 16 or Node 18 to build your project, or explicitly specify a runtime in your adapter configuration.
project/settings/build and deployment , set node.js version
I checked the logs for the project you shared. This build threw Unsupported Node.js version: v22.17.1. Please use Node 16 or Node 18 to build your project, or explicitly specify a runtime in your adapter configuration from @sveltejs/adapter-vercel. Based on that, it sounds like you need to update some packages to newer versions compatible with Node.js 22.
Thanks for sharing the project build link to make it easier for us to find! I removed the link from your post, just to be safe.
