gcloud authentication problem on TTS python script

Question

I am following this document: https://cloud.google.com/text-to-speech/docs/quickstart-client-libraries#client-libraries-install-python

I have followed the instructions. I get an error when I run the provided Python code ("Create audio data" section).

First Try:

It appears the problem is with authentication. I authenticated with gcloud init.

The above exception was the direct cause of the following exception:

Second Try Update:

I ran this gcloud auth activate-service-account [email protected] --key-file="C:\webDev\keys\google-cloud\tts-alphax-nov-b101c56c70b7.json" --project=tts-alphax-nov

This resulted in: Activated service account credentials for: [[email protected]] I then ran the python again and this was the error I got.

Try this: set GOOGLE_APPLICATION_CREDENTIALS=path_to_service_credentials.json in your command prompt shell. Then try the program again. — John Hanley
I got a slightly different (error)[docs.google.com/document/d/… — normandantzig

This error message is usually thrown when the application is not being authenticated correctly due to several reasons such as missing files, invalid credential paths, incorrect environment variables assignations, among other causes. Keep in mind that when you set an environment variable value in a session, it is reset every time the session is dropped.

Based on this, I suggest you to validate that the credential file and file path are being correctly assigned (avoiding to include blank characters when setting the GOOGLE_APPLICATION_CREDENTIALS env variable), as well as try to explicitly specify your service account file directly into your code by adding the following credentials code to your solution:

from google.oauth2 import service_account

credentials = service_account.Credentials.from_service_account_file('<serviceAccountPath>.json')

texttospeech.TextToSpeechClient(credentials=credentials)
