Axios error: … .data.pipe is not a function

So I am basically trying to use axios to download a image from a url, but I get this error:

TypeError: streamResponse.data.pipe is not a function

My function for doing this image download is below (note that this is inside a class):

/**
 * Download poster
 */
async downloadPoster() {

    // Writer stream where we want to download the poster image
    const writer = fs.createWriteStream(this.poster.file);

    // This grabs the second part of the image url that we want
    const resultsResponse = await axios({
        url: this.poster.url,
        method: 'GET',
        responseType: 'json',
        adapter: httpAdapter
    });

    // Zero results
    if (resultsResponse.data.total_results <= 0) {
        logger.log(language[Config.language].posterNotFound + this.movie.title, 'error');
        return false;
    }

    // Create the poster download URL
    var posterDownloadUrl = new URL(Config.api.posterUrl + resultsResponse.data.results[0].poster_path);

    const streamResponse = await axios({
        url: posterDownloadUrl,
        method: 'GET',
        responseType: 'stream',
        adapter: xhrAdapter
    });

    // Write data
    streamResponse.data.pipe(writer);

    return new Promise((resolve, reject) => {
        writer.on('finish', resolve);
        writer.on('error', reject);
    });

}

        writer.on('error', reject);
    });

}

I assume that the adapter for a stream response is the xhr one. Anyways, I have tried both adapters and both gives the exact same error. Both requests does happen though (I can see them in the devtools).

And so there’s no confusion, I have the adapters imported at the top of the file:

const httpAdapter = require('axios/lib/adapters/http');
const xhrAdapter = require('axios/lib/adapters/xhr');

What could I be doing wrong here?

Got it working by sending the download request over to the main thread. Don’t know why, but seems you can’t access the axios data from a stream in the renderer.js file. Got it working now though after having a look here:
