req.pipe - TypeError: reqPipe is not a function

Question

I'm trying to upload some files with AWS using the busboy module, but when I use req.pipe to say that busboy is controlling the response, I get the error:

req.pipe is not a function.

Here is my code:

const uploadDeArquivos = async (reqHeaders, reqFiles, reqBody, reqPipe) => {
    let bb = busboy({ headers: reqHeaders });

    bb.on('finish', async () => {
        const { salaoId, servico } = reqBody;
        let errors = [];
        let arquivos = [];

        if(reqFiles && Object.keys(reqFiles).length > 0) {
            for (let key of Object.keys(reqFiles)) {
                const file = reqFiles[key];
                const splitName = file.name.split('.');
                const fileName = `${new Date().getTime()}.${
                    splitName[splitName.length - 1]
                }`;
                const path = `servicos/${salaoId}/${fileName}`;

                const response = await aws.uploadToS3(file, path);

                response.error 
                    ? errors.push({ error: true, message: response.message })
                    : arquivos.push(path);
            };
        };

        if (errors.length > 0) throw errorThrow(500, errors[0]);

        // Criar Serviço
        let jsonServico = JSON.parse(servico);
        const novoServico = await Servico(jsonServico).save();

        // Criar arquivo
        arquivos = arquivos.map(arquivo => ({
            referenciaId: novoServico._id,
            model: 'Servico',
            caminho: arquivo,
        }));

        await Arquivo.insertMany(arquivos);

        return { 
            servico: novoServico, 
            arquivos 
        };
    });

    reqPipe(bb);
};

const newServico = async (req, res, next) => {
    try{
        const newServico = await uploadDeArquivos(req.headers, req.files, req.body, req.pipe);
        return res.status(201).json(newServico);
    } catch(error){
        next(error);
    }
};

router.post('/', newServico);
