Error: An unexpected symbol '||=' was found

I'm facing an issue while trying to create a nextjs project with PDFViewer using @react-pdf-viewer. The error I encountered is "SyntaxError: Unexpected token '||=' when collecting pages.

This problem seems to be originating from pdf.js in the node_modules directory. To resolve it, I attempted to replace ||= with || in pdf.js, which successfully eliminated the error during the build process.

However, the challenge now arises while deploying on hosting as I need to download pdf.js again via yarn install. This could potentially undo the changes I made earlier. Any advice on how to navigate this situation?

Answer №1

If you encounter this issue, it is likely because your current version is lower than 15. To resolve it, make sure to update to a version that is equal to or greater than 15.0.
