Error executing query

Community Cloud

Hello,

I’ve looked in vain for an answer to my issue. I have a db web app that runs fine locally and I have deployed for users to access. It has predefined SQL queries that can be executed with results from BigQuery. It uses pandas_gbq library to process the queries. I have the secrets file saved accordingly and the contents in my app’s secret section. I get the following error message when I try and execute a query:

pandas_gbq.exceptions.GenericGBQException: Reason: 401 POST https://bigquery.googleapis.com/bigquery/v2/projects/s4a-prod/jobs?prettyPrint=false: Request had invalid authentication credentials. Expected OAuth 2 access token, login cookie or other valid authentication credential. See Integrating Google Sign-In into your web app  |  Google Sign-In for Websites  |  Google Developers.

BigQuery API is enabled. In the Credentials tab I have an API key with HTTP referrers and an OAuth 2.0 Client ID. BigQuery API and BigQuery Data Transfer API are the API restricted. I’ve added https://oauth2.googleapis.com/token in the Authorized redirect URI field and https://share.streamlit.io in the Authorized Javascript origins field.

I don’t know what I am missing. Any help would be appreciated!

That’s a strange one @Mark_Moralls. When you copied your secrets into the interface, did you make sure to convert it to toml instead of the JSON that Google usually provides?

Hi @Mark_Moralls -

We played around internally a bit, we think this might be a case of not setting a project_id. Because Streamlit Cloud is hosted on Google Cloud, it looks like the Python library infers a project you don’t have access to.

So check that value in the Secrets interface and let us know if that resolves it.

Best,
Randy

Hi Randy,

Thanks for looking into my issue. Yes, it was a strange one and I did verify the secrets file to TOML format. I thought the credentials line was enough to make the connection to the project id.

credentials = service_account.Credentials.from_service_account_info(
st.secrets[“gcp_service_account”]

So after going back to the pandas_gbq documentation, I did set a project id variable and added project_id and credentials to each of my df variable entries:

df = pandas_gbq.read_gbq(contents, project_id, credentials=credentials)

So now each query works as I intended! Glad this was resolved. Thanks again!
