Original GitHub issue: https://github.com/fsouza/fake-gcs-server/issues/218

I was playing around with the docker fake-gcs-server. Based on nodeJS example from this repo, I copy-pasted the sample code and modified it a little:

process.env["NODE_TLS_REJECT_UNAUTHORIZED"] = 0;
process.on("unhandledRejection", err => {throw err});

async function testOperation() {
  
  const {Storage} = require("@google-cloud/storage");

  const storage = new Storage({
    apiEndpoint: "127.0.0.1:4443",
    projectId: "test",
  });

  const bucket = storage.bucket('photos');

  bucket.create()
    .then(function(data) {
      const b = data[0];
      console.log(b.name)
    })

  const file = bucket.file('note.txt');
  const contents = 'Happy working prototype!';

  file.save(contents).then(function() {});

}

testOperation().then(console.log);

When I run it, I got:

process.on("unhandledRejection", err => {throw err});
                                         ^

Hi @Fruzenshtein, thanks for opening this issue! This is interesting, the bucket creation succeeds but it looks like when you call bucket.file() the SDK doesn't persist the client configuration. You probably need to dig into their docs or source code on how to properly set that.

Closing as this appears to be an issue with the SDK, not the server.

Hi, I found out that adding {resumable:false} when creating a writestream works
