Hi Everyone,
1st post !
I’m using the Google Vision API … all working fine for certain images - 1 face, 4 faces, 6 faces … all good
I then try a crowd photo with at least 50 faces on and I receive the trace below …

BookmarkManager bookmarkManager)The Google Vision Try It web page handles the image correctly - categorises it etc etc
I’ve tried various values on the UIPath,GoogleVision.Activities.FaceDetection.Input.MaxNumberOfResults property but still get the above error.
the image file I’m looking at appears to be within the size & number of pixels specificed.
I’m using the imagepath property to pass in the location of the image
Anyone able to provide any guidance or a solution ?
Many thanks in advance
/P
