React Admin The dataProvider returned an empty response for 'update'

I'm creating a React Admin project with a Drf Api, the thing is, when I update the image field of one of my models, it updates, and everything works, but throws the next error: "The dataProvider returned an empty response for 'update'.".

I checked at the network section in the development tools, and it does receive a response from the api

Api response

Here is the React Admin data provider code:

const dataProvider = drfProvider('http://127.0.0.1:8000')

const myDataProvider = {
    ...dataProvider,
    update : (resource, params) => {
        if(!params.data.image) {
            return dataProvider.update(resource, params)
        }
        if (!params.data.image.rawFile) {
            delete params.data.image
            return dataProvider.update(resource, params)
        }
        return convertFileToBase64(params.data.image).then(image => {
            dataProvider.update(resource, { 
                ...params,
                data : {
                    ...params.data,
                    image : image
                }
            })
        })
    }
}

const convertFileToBase64 = file =>
    new Promise((resolve, reject) => {
        const reader = new FileReader();
        reader.onload = () => resolve(reader.result);
        reader.onerror = reject;

        reader.readAsDataURL(file.rawFile);
    });

export default myDataProvider; ```
