Hey,

I’m not entirely sure about the specifics of what you’re deploying—this is just an educated guess—but ensure you’re using the right Node version as required by your project (see https://docs.render.com/node-version) . Also, check you’re using the correct version of the ‘bcrypt’ library. There’s a helpful discussion on Stack Overflow regarding an issue with installing ‘bcrypt’ via npm, which might be relevant to your case. Here’s the link for that: Error installing bcrypt with npm.
