Deploy fails because of incompatible module

I tried setting my node version using a deployment environment variable in netlify (NODE_VERSION) but it would not work. after a bit of looking around i found that my node version was being set via the netlify.toml file which is used for gatsby. I set my version in the netlify.toml file and my build version started using the correct node version.
