I did have node version 18 installed in the system prior to this. I thought that may be giving the issue so I uninstalled that version and installed version 14. I don't have any idea why sam is running it on node version 18

Answer 1

I just recently looked into this as well since Node 18 is the current LTS. If you go to the Serverless Image Repository you'll see that AWS SAM doesn't currently have an image for Node 18. There's an explanation about this in this Github issue.

seems like it's supported now – Symphony

Answer 2

You can now update your sam cli, it now supports nodejs v18

Here is the list for all suported languages
