I’ve been trying to solve this too. With the help of some others. Hoping for the “extract content from image” card to analyse a WhatsApp image sent by the user. I currently have a ‘wait for user input’, then the ‘extract content’ card next. Leaving the url blank always seems to return an error (400). Entering a workflow variable into the url field does make it work but only if you pre fill the variable. I’ve not managed to get the image sent from the user analysed yet. I think it needs some custom code to get the irl of the image sent and add it to the variable.
