TypeError: Cannot read properties of undefined

I’m Using node.js and mongodb for my backend project. I have pushed the code in github. When I’m deploying the project, this error is showing in log.

Node.js v20.15.1 ==> Using Node version 20.15.1 (default) ==> Docs on specifying a Node version: Setting Your Node.js Version – Render Docs ==> Using Bun version 1.1.0 (default) ==> Docs on specifying a bun version: Setting your Bun Version – Render Docs ==> Running ‘node index.js’ /opt/render/project/src/node_modules/path-to-regexp/index.js:63 path = (‘^’ + path + (strict ? ‘’ : path[path.length - 1] === ‘/’ ? ‘?’ : ‘/?’)) ^ TypeError: Cannot read properties of undefined (reading ‘length’) at pathtoRegexp (/opt/render/project/src/node_modules/path-to-regexp/index.js:63:49) at new Layer (/opt/render/project/src/node_modules/express/lib/router/layer.js:45:17) at Function.use (/opt/render/project/src/node_modules/express/lib/router/index.js:475:17) at Object.

This is the full errror. Can anyone please solve it?

It looks like you’re passing something undefined as a route. path-to-regexp is used by express. You might find it helpful to examine how your routes are being defined and whether they are actually defined.
