IBM has recently made some changes to their APIs.
Therefore, before we can start, we need to install a patch:
Log in to the Raspberry Pi 4 via Terminal (Mac) or Putty (Windows):
Mac: ssh pi@raspberrypi
Windows: Open Putty and enter 'raspberrypi' at Host Name and then click on the 'Open' button. Type 'pi' when the user name is requested.
Password is 'raspberry' by default
Now run the following commands to install the patch:
cd .node-red/nodes/node-red-contrib-tjbot/tjbot/
wget -N https://raw.githubusercontent.com/chunyianliew/node-red-contrib-tjbot/chunyianliew-patch-1/tjbot/config.html
sudo reboot now
We have now finished installing the patch.
