React native image upload to graphQL api

Currently I have an existing graphql api that takes and array of images, docs, .pdf attachments etc that is being uploaded using apollo client to a graphQL api. Im trying to upload attachments to the same api using react query in a react native app and its not working.
2 X developers tried and gave up. No chances or junior / intermediate developers DO NOT apply. Only seeking senior developers that can get this working asap.
