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. What do I do? Attached is the code and what the bot says. Thank you very much for your help it is much appreciated!

Hi, The code calls the localhost, Botpress don't have access to your localhost. You can use NGROK to expose/publish your API online, then use the NGROK URL in the execute code.

Thank you very much, however, now I am having trouble downloading ngrok from the command prompt. Here is what it says

Hi, did you install ngrok?
