ComputerVisionClient or Xamarin Essentials Error - Invalid URI: The format of the URI could not be determined when calling method ReadInStreamAsync - azure

Question

So I am capturing a photo and opening a stream using Xamarin.Essentials 1.7 MediaPicker built into Essentials.
When I call the ReadInStreamAsync(stream) method in Computer Vision Client, I get an error and my Xamarin.Forms app breaks inside the method: 'Invalid URI: The format of the URI could not be determined.'
This is the stream.Name value - '/data/user/0/com.companyname.xamphotoappdemo2/cache/2203693cc04e0be7f4f024d5f9499e13/198fd32db9cc4be38a493325974fa138/d964251252fc4963aca94339d73a8007.jpg'
This is my code:
var file = await MediaPicker.CapturePhotoAsync(new MediaPickerOptions
{ Title = "Please take a photo" });
if(file != null)
{
var stream = await file.OpenReadAsync();
chosenImage.Source = ImageSource.FromStream(() => stream);
// 2. Add OCR logic.
var client = Authenticate(ApiSettings.subscriptionKey, ApiSettings.endpoint);
var text = await client.ReadInStreamAsync(stream);
//after the request, get the operation location
string operationLocation = text.OperationLocation;
//we only need the operation ID, not the whole URL
const int numberOfCharsInOperationId = 36;
string operationId = operationLocation.Substring(operationLocation.Length - numberOfCharsInOperationId);
//Get the ocr read results
ReadOperationResult results;
do
{
results = await client.GetReadResultAsync(Guid.Parse(operationId));
}
while ((results.Status == OperationStatusCodes.Running || results.Status == OperationStatusCodes.NotStarted));
var readResults = results.AnalyzeResult.ReadResults;
var expirationDates = from page in readResults
from line in page.Lines
where line.Text.Contains("EXPIRES") && line.Words.Count == 4
select line.Words[3].Text;
expirationDate.Text = expirationDates.ToString();
photoPath.Text = file.FullPath;
The image is displaying as expected in the XAML Image control and that is reading the image source from the stream, so is this a bug in the ReadInStreamAsync method?
