Permission Denied: 403 Dialogflow API has not been used in project before or it is disabled. about python-dialogflow HOT 3 CLOSED

@Hesmond, did you follow these instructions carefully: https://github.com/dialogflow/dialogflow-python-client-v2/blob/master/samples/README.rst#before-you-begin? In particular, are you passing --project-id flag when calling detect_intent_texts.py?

from python-dialogflow.

@lukaszbk, yup I followed the instructions there, only thing is I didn't use the sample agent, I created my own called "Small-Talk".

As for the command trigger, I used the following command to trigger:
python detect_intent_texts.py --project-id small-talk-b4c3b --session-id session-play-1 "hi"

also tried,
python detect_intent_texts.py --project-id "small-talk-b4c3b" --session-id "session-play-1" "hi"

I got my project id from

Dialog flow console > agent > settings > General > Google Project > Project ID

As for "4. Set up authentication", I followed the steps here in the verify authentication section, got 2 buckets in the print statements, I assume that means I have successfully verified authentication.

from python-dialogflow.

Quick Update:
I created another agent in DialogFlow, did the entire process again and triggered the file, still hitting the same issue.

python detect_intent_texts.py --project-id small-talk-v2 --session-id session-play-1 "hi"

Weirdest part is, even after changing the project id, it is still giving me the following error:

google.api_core.exceptions.PermissionDenied: 403 Dialogflow API has not been used in project 563584335869 before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/dialogflow.googleapis.com/overview?project=563584335869 then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry.

Got it to work after setting my google environment variables:

set GCLOUD_PROJECT=your-project-id
set GOOGLE_APPLICATION_CREDENTIALS=/path/to/service_account_file.json
