When doing a query using SDK\'s CLI like this:
bq query \"select * from [project]:[dataset].[table]\"
Response is:
BigQuery error in query operatio
First, as mentioned in early comments and answers, ensure that you have enabled the BigQuery API.
If you still get the same error message, you are most likely using the project name where you should be using the project id.
The project id is the project name followed by a number, and you should be able to find it using the Console.
If you are sure you have the API enabled and the id and the name sorted correctly, try checking the Google Cloud Status Dashboard for any ongoing BigQuery outages.
