I am trying to get the knowledge base from botpress and flowise to work, but for some reason it keeps saying an error occured when I ask it a raw input question. I figured out that the code calls the localhost, Botpress don't have access to my localhost. You can use NGROK to expose/publish your API online, then use the NGROK URL in the execute code. However, when I try to download ngrok through a command prompt it says an error occurred instead of taking me to the next step. What do I do about this? Attached is a picture of what it shows.
