New problem receiving image

[Maximo-Verdondoni]

Hi guys, im using wuzapi with node-red for a chatbot.
Last wednesday the chatbot works properly but today i have a new problem.

When I send an image to the bot in the payload I only receive the buffer of the photo but last week I received a payload that was an object with information about the person who sent the message and I received the image in .enc with the data to decrypt it (mimetype, FileENCSHA, FileENCSHA256, etc) and went through an api to pass it to base64
Did the API have any changes these days? I don't understand why now the image arrives different

Thank you
