Exif - Metadata

Hi, I’m in an ionic project for the client side and for the server side java i’m sending with the plugin camera preview/image-picker the base 64 image that the server side receives and display the metadata info. but i don’t know what happen because it brings back the GPS empty but if i test this uploading the image to a page that converts to base 64(https://www.base64-image.de/) then I send that data to another page in order to test this(http://metapicz.com/#landing) it brings me the GPS data that i need.
