Hi i am working on Google Cloud API, when i try to run the demo program given on GC documentation, for the following code 

from google.cloud import language
from google.cloud.language import enums
from google.cloud.language import types

# Instantiates a client
client = language.LanguageServiceClient()

# The text to analyze
text = u'Hello, world!'
document = types.Document(
    content=text,
    type=enums.Document.Type.PLAIN_TEXT)

# Detects the sentiment of the text
sentiment = client.analyze_sentiment(document=document).document_sentiment

print('Text: {}'.format(text))
print('Sentiment: {}, {}'.format(sentiment.score, sentiment.magnitude))

The code doesn't run when it hits this statement sentiment = client.analyze_sentiment(document=document).document_sentiment

and gives the following long error

Traceback (most recent call last):

  • Are you running this code on your desktop, meaning not on a Google Compute instance? You have the question tagged `google-cloud-functions`. The error is caused by not being able to access the metadata server to get credentials (access tokens). – John Hanley Oct 22 '19 at 12:33
  • i am actually using Google Cloud's terminal using a VM. – lalith Shankar Oct 23 '19 at 09:19
  • i have debugged the code and i am getting a Traceback and Attribute Error File "", line 1, in AttributeError: 'tuple' object has no attribute 'score' for e in entities: ... print(e.name, e.entity_type, e.metadata, e.salience) ... Traceback (most recent call last): File "", line 2, in – lalith Shankar Oct 23 '19 at 09:22

I’ve tried to replicate the issue but I was having a different error at my local test, since after the retry logic it failed due to a request timeout. Then I tried the same code at the cloud functions environment and it was working correctly.

My local env was the Cloud Shell, I’m afraid that this could be a problem from a recent outage in cloud networking.

To debug into your local environment you can use this tutorial.
