I am having a hard time with the Dialogflow v2 Java Client Library and Spring-Boot in Eclipse.
Please note, I have seen the Stack Overflow posts regarding these methods with api.ai v1 client libraries and the helpful Google links regarding how these api calls are made. I am dumb, please help.
Specifically, I am trying to send user input to invoke an intent from my Dialogflow agent, and I have created a RestController to do so with the @RestController annotation placed by my class definition.
For some reason, even though I have created a service account and I chose the Dialogflow role for it in my GCP account, I am still receiving a PERMISSION_DENIED error.
I will post my code in the following order:
- My Spring Rest Controller Class
- My Spring Application Class
- My Spring pom.xml
- The exception raised in the console by the Tomcat server
- The exception printed on my Google Chrome browser when I ping my mapped url
THE EXCEPTION ON MY WEBPAGE suggests going to this link to enable permission, but when I go to it the page just says "The API "dialogflow.googleapis.com" doesn't exist or you don't have permission to access it Tracking Number: 3690215267179057879"

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
