Troubleshooting

Jupyter Notebooks

Make sure the pip install ran correctly. You might need to restart the kernel and run the cells from the top after the pip install runs the first time.
Many of the cells rely on variables that are set in earlier cells. Some of these are cleared in later cells. Start over at the top when troubleshooting.
Many of the cells rely on service credentials from Bluemix that are set in earlier cells. Make sure to add your service credentials correctly.
If the Start Websocket client step throws an error as shown below, please refer to the step Update the websocket URL in the notebook in Section 10 of the documentation.
```
    --- response header ---
    HTTP/1.1 500 Error
    X-Backside-Transport: FAIL FAIL
    Content-Type: text/xml
    Connection: close
```

Node-RED

Refer to sections 5 & 6 in the documentation regarding the usage of Node-RED flow. Please make sure to update the Node-RED based URL in the json file before importing it into the Node-RED editor.

Watson Assistant

Make sure that the Watson Assistant service credentials which had been noted down in step 2 and and Workspace ID which had been noted down in step 3, has been updated in the Watson Assistant node in Node Red Flow according to step 5.
