Describe the bug

When deploying my project to Vercel, this error raises:

Cannot find module '../endpoint/endpointResolver'
Require stack:
- /var/task/node_modules/@aws-sdk/client-s3/dist-cjs/auth/httpAuthSchemeProvider.js
- /var/task/node_modules/@aws-sdk/client-s3/dist-cjs/index.js
- /var/task/public/scripts/s3.js
- /var/task/app.js
- /var/task/___now_launcher.js
- /var/runtime/index.mjs
Did you forget to add it to "dependencies" in `package.json`?

When I run it locally, it works fine.

Additional Information/Context

I import it to my s3.js file using:

The file @aws-sdk/client-s3/dist-cjs/endpoint/endpointResolver.js exists in our distributed artifact, which can be verified by the code browser on https://www.npmjs.com/package/@aws-sdk/client-s3?activeTab=code. Did your build or deployment process omit it?

[dwnppoalt]

I don't think its in the build or install process. My project doesn't have a build command, and it only installs the dependencies through

npm install

Hi @dwnppoalt - this may be caused by a mismatch in the versions of the AWS SDK installed locally and on Vercel's deployment environment. What does your package.json look like?

One suggestion would be to update @aws-sdk/client-s3 package to the latest version with npm install @aws-sdk/client-s3. Please share your package.json if issue persists.

@aBurmeseDev I installed the AWS SDK on my local machine using npm install @aws-sdk/client-s3@latest. It installed version 3.682.0, which I used in my Vercel deployment.

This is my package.json:
