[SOLVED] Can't set project in Cloud Natural Language API

Can't set project in Cloud Natural Language API

I'm using the api sample as found here.

Running gcloud config list shows my default project as project = multichoice-insights

Important extract of the code shows that I get the default credentials:

  credentials = GoogleCredentials.get_application_default().create_scoped(
  ['https://www.googleapis.com/auth/cloud-platform'],
)

However, when I try and use the api, I get the error message:

googleapiclient.errors.HttpError: <HttpError 403 when requesting 
https://language.googleapis.com/v1beta1/documents:analyzeSentiment?
alt=json returned "Google Cloud Natural Language API has not been used 
in project google.com:cloudsdktool before or it is disabled. Enable it 
by visiting
   https://console.developers.google.com/apis/api/language.googleapis.com/over
view?project=google.com:cloudsdktool then retry. If you enabled this 
API recently, wait a few minutes for the action to propagate to our 
systems and retry.">

I think this shows that the project used: project=google.com:cloudsdktool

How can I change this to project-name?

I have enabled this api in the console.

Solution

For anyone that has this issue:

One needs to set their Environment variable. If you are using virtualenvs, set the variable as follows.

In the file: .virtualenvs/env_name/bin edit the file activate to contain the following line:

GOOGLE_APPLICATION_CREDENTIALS=/abs/path/to/credentials.json

This credentials.json is donwloaded from the api page. Full instructions can be gathered from here

Hope this helps someone.
