Unit test jest upload  issue 
I am having the following error

```
{
      errors: [
        GraphQLError [Object]: Variable "$file" got invalid value {}; Upload value invalid.

      ]
    }
```

Right now is only failing in the unit test, with the productive app it is working the uploading file functionality. I had the same error message with the productive app and I solved it adding the following to the package.json
 
```
 "resolutions": {
    "graphql-upload": "^11.0.0"
  },
```

I will share with you the unit test code

```
    test('Add profile picture', async () => {
      const fileName = 'logo.png';
      const file = fs.createReadStream(
        path.resolve(__dirname, `../utils/test/factory/${fileName}`)
      );
      const fileStream = new Promise((resolve) =>
        resolve({
          createReadStream: () => file,
          stream: file,
          filename: fileName,
          mimetype: 'application/png',
        })
      );
      const { id } = await createCoach({
        ...userData,
        userType: UserType.US,
      });
      await createRefreshToken({
        ...userData,
        valid: true,
        id,
      });
      const response = await graphqlTestCall({
        source: addProfilePictureMutation,
        variableValues: {
          id: { id },
          file: fileStream,
        },
      });
      console.log(response);
      expect(response.data.addProfilePicture).toEqual({
        id,
        profilePicture: true,
      });
      expect(sharp.mock.calls.length).toBe(resolutions.length);
    });
```

In addition this is the graphqlTestCall code

```
import { graphql, GraphQLSchema } from 'graphql';
import { buildSchema, Maybe } from 'type-graphql';
import { allResolvers } from '../../resolvers';
import { customAuthChecker } from '../../middleware/auth';
import { mockShortToken } from './shortToken';

interface Options {
  source: string;
  variableValues?: Maybe<{
    // eslint-disable-next-line @typescript-eslint/no-explicit-any
    [key: string]: any;
  }>;
  shortToken?: string;
}

let schema: GraphQLSchema;

export const graphqlTestCall = async ({
  source,
  variableValues,
  shortToken = mockShortToken(),
}: Options) => {
  if (!schema) {
    schema = await buildSchema({
      resolvers: allResolvers,
      validate: true,
      authChecker: customAuthChecker,
    });
  }
  return graphql({
    schema,
    source,
    contextValue: {
      ...(shortToken && {
        req: {
          headers: {
            authorization: `Bearer ${shortToken}`,
          },
        },
      }),
    },
    variableValues,
  });
};
