TypeError: cannot read property 'speak' of undefined

[ssuppan]

This is the second time I've installed node-red and node-red-contrib-tjbot.
The first time node-red had issues with visual-recognition and then started to get confused with "see" and "wave" nodes. The second time node-red had issues with tone_analyzer credentials which weren't really required for my flow. It also could not understand the 'speak' node after running it a couple of times.

This usually happens when the underlying TJBot library can't be instantiated.

Please check the logs of Node-RED and reply with any errors that are being logged, aside from the method of undefined you've posted. If you automatically start node-red, use the commands node-red-stop and node-red-start to stop and restart node-red manually.

Thank you for getting back to me JeanCarl.
The errors which I get on the console logging are:
[tjbot-config:a0f3080.0a26f8] Error: pigpio error -1 in gpioInitialise
[tjbot-shine:15ffc754.ac1719] TypeError: Cannot read property 'shine' of undefined

I would really like to use node-red if at all possible. How do I get around this? Is there some procedure you could prescribe for me to debug this issue.

[jeancarl]

Are you running Node-RED as root?

Creating a new TJBot configuration and reconnecting the flows made it work for me. Seems like an extensive solution if you have bigger/many flows, though.
