Upload to images using batch api returns 103: invalid token

📹Images / Stream

Good evening, I’m trying to upload an image using the batch API. I’m retrieving a batch token successfully but the call to upload an image with the batch token as the bearer token returns a 103 error. Does anyone know how to help please? I’m calling https://batch.imagedelivery.net/images/v1 with the same parameters as I would use if I weren’t using the batch endpoint (which works, by the way)
