API using functions doesnt give expected output (same code gives expected output elsewhere)

so I have a express sever hosted on netlify at https://meek-gecko-000509.netlify.app/ using netlify functions, everything works almost fine but one specific api endpoint doesnt , the /api/png for example main version running in other place will show hypixel’s logo at https://heatblock.esb.is-a.dev/api/png/mc.hypixel.net while the sever hosted at netlify returns a eroor image at https://meek-gecko-000509.netlify.app/api/png/mc.hypixel.net while all other endpoints work

If this is the code: hb-test/index.js at main · EducatedSuddenBucket/hb-test, then it’s not in the expected format. You can’t have:

module.exports.handler = serverless(app);
module.exports = serverless(app);

This won’t work as you’re essentially doing the following:

module: {
  exports: {
    handler: serverless(app)
  }
}

and then, you’re doing:

module: {
  exports: serverless(app)
}

So the handler property is removed which is exactly what the error says:

Runtime.HandlerNotFound - index.handler is undefined or not exported

Please refer to: Express on Netlify | Netlify Docs

i was just testing by editing my code , the time i crated the thread i had only

module.exports.handler = serverless(app);

also i reverted back to using that so pls check now

I’m not sure what you’re trying to do. Why is it not possible to simply use fetch()? When I’m trying to load mc.hypixel.net, I never get a response myself.

i made a video showing what is happening: https://www.youtube.com/watch?v=mB-PFp8RTAw
other api endpoints work fine

bumping thread to get follow up

fixed by replacing this

module.exports.handler = serverless(app);

With this

module.exports.handler = serverless(app, {
  binary: ['image/png'],
});
