typescript - createreadstream is not a function + graphql-upload

Question

I'm trying to upload a file from Angular using nodejs, express and graphql-upload. I coded and when I try to upload, my server says that createreadstream is not a function and I don't know where is the problem. I watched the same questions but older. Please somebody can help me? If you need more information, please, let me know. I'm' junior asking. Thank you in advance

Nodejs version 14.13.1

Grapql-upload latest

typescript

My code is the next one:

Mutations.ts

    import { IResolvers } from 'graphql-tools';
    import fs from 'fs'
    import { processUpload } from '../../lib/upload';
    
    const resolversColorMutation: IResolvers = {
    
      Mutation: {
        
       
        singleUpload: (_, { file }, { cloudinary }) => processUpload(file, cloudinary)
    
        }
      }
    
export default resolversColorMutation

upload.ts

const storeFyleSystem = ({ stream, filename }: any, userId: string) => {
    const path = `${UPLOAD_DIR}/${filename}`;
    const id = userId;
    return new Promise((resolve, reject) =>
        stream
            .on('error', (error: any) => {
                if (stream.truncated) {
                    // Delete the truncated file.
                    // Borar el fichero local
                    fs.unlinkSync(path);
                }
                reject(error);
            })
            .pipe(fs.createWriteStream(path))
            .on('error', (error: any) => reject(error))
            .on('finish', () => resolve({ id, path }))
    );
};


const UPLOAD_DIR = './uploads';


export const processUpload = async (upload: any, cloudinary: any) => {
    mkdirp.sync(UPLOAD_DIR);
    const { createReadStream, filename, mimetype } = await upload;
    **const stream = createReadStream()**;
    const { id, path }: any = await storeFyleSystem({ stream, filename }, 'theName');

    fs.unlinkSync(path);

    return { id, path, filename, mimetype};
};
