React-Native expo-google-drive-api-wrapper not uploading base64 images - react-native

Question

I pick an image using ImagePicker from 'expo-image-picker'. Said image is stored in base64Ref
If I send the file to Google Drive using b64 = false the upload works fine.
If I use b64 = true the file is never sent. All The info I can get is:
response
{
"type": "default",
"status": 400,
"ok": false,
"statusText": "",
"headers": {
"map": {
"content-type": "text/plain; charset=utf-8",
"date": "Tue, 21 Dec 2021 20:03:22 GMT",

}
},
"url": "https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart",
"bodyUsed": false,
"_bodyInit": {
"_data": {
"size": 25,
"offset": 0,
"blobId": "d811ac9c-431d-4582-8de4-d31adb93ca8f",
"__collector": {}
}
},
"_bodyBlob": {
"_data": {
"size": 25,
"offset": 0,
"blobId": "d811ac9c-431d-4582-8de4-d31adb93ca8f",
"__collector": {}
}
}
This is the code
const b64 = false;
Drive.files.createFileMultipart(
"data:image/png;base64,"+base64Ref.current,
"image/png", {
parents: ["root"],
name: "MyImage.png"
},
b64)
.then((response) => {
let q = response;
console.log("response");
console.log(JSON.stringify(q));
})
