Gatsby Build Succeeding Locally but Failing Deploy

My Gatsby site is building perfectly fine locally when I run netlify build with the Netlify CLI. But When I push the code to Github, triggering a branch deploy, the build fails.

Immediately after ‘Executing user command: gatsby build’, there’s a Syntax error that seems to be coming from the gatsby-cli package. But the fact that it’s working just fine locally is what is weird. I’ve even run npm install -D gatsby-cli just in case with no improvement. The issue is only on my project’s development branch. Main branch builds no problem.

Any ideas on what could be causing this issue? Any help is much appreciated!
