upload from Model SDK (Angular)

[Furkan Suv]

Description/Steps to reproduce

I'm trying to upload attachement from Angular APP via Loopback SDK Model. Uploading from Postman it's working fine.

Loopback version:
├── @mean-expert/loopback-sdk-builder@2.3.1
├── loopback@3.25.1
├── loopback-boot@2.28.0
├── loopback-component-explorer@6.3.1
├── loopback-component-storage@3.6.1
├── loopback-connector-mssql@3.3.0
├── loopback-connector-mysql@5.4.0

Setups:

Server Model:

Attachement.json:
{
"name": "attachment",
"plural": "attachments",
"base": "Model",
"idInjection": true,
"options": {
"validateUpsert": true
},
"properties": {},
"validations": [],
"relations": {},
"acls": [],
"methods": {}
}

App Source:

test.component.html
`<form [formGroup]="form" (ngSubmit)="onSubmit()">

`

test.component.ts
constructor(
private _attachement:AttachmentApi
) { }

//Create form
form(mitglied: Mitglied) {
form = this.fs.group({
'file': ['']
})
}

//send to loopback server
onSubmit(){
this._attachement.upload('demo', this.form.value.file)
.toPromise()
.then(res => {console.log(res)} )
}

Once I submit the form, on Google Chrome Dev tools Network shows the upload "pending" and after 4 Minutes it fails:

Could you please help me?
