having a bug that I can’t wrap my brain around and hoping someone can assist.

I have a React module that does the following with a file:

async function uploadFile(file, typeSent) {
        console.log("SENT FILE:")
        console.log(file)
        let formInfo = new FormData();
        formInfo.append("file", file)
        formInfo.append("name", file.name)

        const requestOptions2 = {
            method: "POST",
            body: formInfo,
            redirect: "follow"
        };

        console.log("ATTEMPTING UPLOAD:")
        await fetch("https://blah.herokuapp.com/upload-files", requestOptions2)
            .then((response) => response.json())
            .then((response) => {
                console.log("UPLOAD RESULT: ")
                console.log(response)
            })
            .catch((error) => {
                console.log("Upload error?")
                console.error(error)
            });
}

this succesfully sends the file to the server, which has a very simple axios function to upload the file:

await axios(config)
            .then(function (response) {
                console.log(JSON.stringify(response.data));
                res.status(200).send({response: response.data})
            })
            .catch(function (error) {
                console.log(error);
                res.status(400).send({errormsg: error.message})
            });

this all works, the server uploads the image and returns a response, however upon performing that fetch within the React module it immediately errors out and provides the following error:

TypeError: Failed to fetch
    at main.js:2:553951
    at c (main.js:2:543956)
    at Generator._invoke (main.js:2:543709)
    at Generator.next (main.js:2:544319)
    at mu (main.js:2:549193)
    at i (main.js:2:549397)
    at main.js:2:549458
    at new Promise (<anonymous>)
    at main.js:2:549337
    at te (main.js:2:554346)

which yeah isn’t too helpful since it’s being minimized by webpack. The file still uploads but the actual response never hits React again, making it “impossible” to actually use the response back from the server…

So, I’m wondering if someone could kindly let me know what I’m missing / having a senior moment on.

I appreciate your help!
