My objective is to send an image to a user on WhatsApp. There are two images in my flow, one uploaded static welcome image, and another image URL passed through as a workflow variable. This was working as expected previously up until the 08th of October 2026. The problem is that neither images are currently rendering in WhatsApp when leveraging the Botpress WhatsApp integration. Image rendering fails silently and is not captured in the logs. I have tested sending images to the WhatsApp API directly via a execute code card. This works successfully - I receive a 200 response and the image renders in WhatsApp as expected. I have uninstalled the WhatsApp integration, and then reinstalled. I am able to have a text based conversation as expected, but images do not render at the key points in the journey. For context, I am using version 4.18.5 of the WhatsApp API and have configured the integration manually (not connected via OAuth).
