EmpathyBot - Google Application Default Credentials not available

Hello, I have tried creating a JSON Key for Google Cloud Vision to finish up the Empathybot but I am having a problem. The JSON Key was created on Windows and transferred to my Raspberry Pi 3 using a USB and placed in /home/pi/ I did this q few times and even renamed it.

The BASHRC file was edited to reflect on this, and the export commend was used before attempting to execute the python file but to no avail. An output is as below:

pi@raspberrypi:~/Desktop export GOOGLE_APPLICATION_CREDENTIALS=vision1-f456725196de.json pi@raspberrypi:~/Desktop sudo python empathy.py
espeak -ven-us+f3 -a 200 -s145 -k20 --stdout ‘Hello! I am empathy bot!’ | aplay

I suspect the problem might be with the user permissions. I would try to go into super user by running su in the command line and then running

export GOOGLE_APPLICATION_CREDENTIALS=vision1-f456725196de.json

You can also try running

sudo export GOOGLE_APPLICATION_CREDENTIALS=vision1-f456725196de.json

Tried that but didn’t work. Same error message. Any other suggestions?

Are you doing all of this in the same directory? The python file, the json file, and the export action?
