Unable to assign the type unknown to an entity with typeorm

Question

I'm having issues using TypeOrm with typescript for a specific project. It seems that typescript is not able to recognize a type coming out from a typeorm entity.

@Entity({
name: "users",
  synchronize: false
})
export default class User {

  private tempPassword:string | undefined;

  @PrimaryGeneratedColumn()
  id!: number;

  @Column({
    type: "text"
  })
  name!: string;
...
}

The code above is my model. So when I try :

let user: UserModel;
try {
  user = await getRepository("User").findOne({name: "test"});

I have the following error on the user variable :

(Which means : unable to assign the type unknown to the type User)

tsconfig.json

{
  "compilerOptions": {
    /* Basic Options */
    // "incremental": true,                   /* Enable incremental compilation */
    "target": "ES2018",                          /* Specify ECMAScript target version: 'ES3' (default), 'ES5', 'ES2015', 'ES2016', 'ES2017', 'ES2018', 'ES2019' or 'ESNEXT'. */
    "module": "commonjs",                     /* Specify module code generation: 'none', 'commonjs', 'amd', 'system', 'umd', 'es2015', or 'ESNext'. */
    "sourceMap": true,                     /* Generates corresponding '.map' file. */
    "outDir": "build",                        /* Redirect output structure to the directory. */
    "rootDir": "./src",                       /* Specify the root directory of input files. Use to control the output directory structure with --outDir. */

    /* Strict Type-Checking Options */
    "strict": true,                           
    "esModuleInterop": true,                   

    /* Experimental Options */
    "experimentalDecorators": true,        /* Enables experimental support for ES7 decorators. */
    "emitDecoratorMetadata": true,         /* Enables experimental support for emitting type metadata for decorators. */
    "resolveJsonModule": true,
  },
  "include": [
    "src/**/*.ts"
  ],
  "exclude": [
    "node_modules"
  ],
}

Is it due to something missing in the tsconfig json ? Big thanks

You have strict: true meaning you have to also check for null / undefined.

let user: UserModel | undefined;

Edit:

I'm thinking that the getRepository(string) signature returns unknown (you can assert its result if you want - as User). Try, getRepository(User)...
