Google-cloud-python: Unsuccessful authentication without errors/warnings

[elcombato]

At first the authentication worked fine and I could see the API requests in the dashboard. But at some point the requests were not showing up anymore in the dashboard API overview.

I created a service account and stored the json file locally. Then I set the environment variable GCLOUD_PROJECT to the project ID and GOOGLE_APPLICATION_CREDENTIALS to the path of the json file.

from google.cloud import speech
client = speech.Client()
print(client._credentials.service_account_email)

Prints the correct service account email.

import io
with io.open(audio_file, 'rb') as f:
    audio = client.sample(f.read(), source_uri=None, sample_rate=48000, encoding=speech.encoding.Encoding.FLAC)
alternatives = audio.sync_recognize(language_code='de-DE')

The resulting transcript is correct, but nothing happens on the dashboard at
https://console.cloud.google.com/apis/api/speech.googleapis.com/overview?project=[project-ID]

I also tried to initialize the client with the function speech.Client.from_service_account_json and to authenticate by installing the Google Cloud SDK and gcloud auth application-default login, but without success.

The error count (Fehler) is increasing here but I don't know how to get additional information.

• Windows 7
• conda environment
• python 3.5.2
• google-cloud-speech 0.23.0

@elcombato thanks for reporting!

The resulting transcript is correct, but nothing happens on the dashboard...

That is pretty strange, because if you're getting results and a 200 response then it should be counting the requests on the dashboard.

Does the request count on the dashboard go up a few hours later?

[elcombato]

@daspecster No it won't show up. The last activity is more than a week old and I used the API daily in the last week.

How can I evaluate that the client is correctly authenticated, to eliminate the possibility of an user error by me?

[dhermes]

You can check the actual authenticated account and project via client._credentials.__dict__ and client._project

[elcombato]

@dhermes With my code from above the object client has no attribute _project.

In client._credentials.__dict__ everything looks fine. Is it expected behavior, that client._credentials.expiry is None after the initialization of speech.Client() and after running client.sample() and sync_recognize() the variable client._credentials.expiry is set to the time of execution?

[theacodes]

It's None at first because the credentials have yet to be refreshed. It should be the time of execution plus one hour after because it refreshed during the execution.

[elcombato]

There is no plus one hour:

from google.cloud import speech
from datetime import datetime

client = speech.Client()

with open("speech.flac", 'rb') as f:
    audio = f.read()
sample = client.sample(audio, source_uri=None, sample_rate=48000, encoding='FLAC')
a = sample.sync_recognize()

print(client._credentials.expiry)
print(client._credentials.expired)
print(datetime.now())

# 2017-03-13 17:24:59.845493
# False
# 2017-03-13 17:25:40.128734

[theacodes]

@elcombato what's datetime.utcnow()?

[elcombato]

ok yea, that is 2017-03-13 16:32:29.200383. So expiry is in utc.

Any thoughts on the missing _project attribute?

[theacodes]

Not sure, you can try executing credentials, project = google.auth.default() and see what it says. You can also explicitly pass the project into the Client constructor.

[elcombato]

Both the credentials and project are correct.

[dhermes]

@daspecster It seems there is no project used in the Speech API. Can you confirm? @elcombato Since that's the case, it seems the relevant project dashboard would be the project that owns the service account credentials.

[daspecster]

@dhermes looking now.

[daspecster]

Yeah, it's using google.cloud.core.client.Client instead of ClientWithProject.

[daspecster]

The Speech authentication docs mention projects but kind of in a general way. Also, it used to be an API key based API so maybe that has something to do with it?

@lukesneeringer is there someone we can ask about how Speech supports project IDs?

[theacodes]

Maybe @gguuss knows?

[gguuss]

re: project IDs on Speech API projects, I have a few contacts from the team but I'm not sure they're on GH.

[lukesneeringer]

@gguuss Any update on this?

[gguuss]

The project ID is only used when the content is a private GCS file.

[lukesneeringer]

Thanks @gguuss. That puts us more or less back where we started; project is not the culprit.
To be honest, I have no idea why the dashboard does not reflect anything, and that is a backend issue... :-/

[elcombato]

The API calls are now showing up on my dashboard after updating to 0.24

[lukesneeringer]

How incredibly bizarre.
Closing this issue. Feel free to reopen if the problem pops back up.
