Try your REST API test from the documentation page here:
https://cloud.google.com/bigquery/docs/reference/rest/v2/jobs/query
If that doesn’t help, try “curl” command from Cloud Shell …
Also .. you are querying a dataset called “9090”. In BigQuery Studio, go to the details of that Dataset and grab a screen shot and post it here. I for one am very interested in seeing the “Data location” property. I’m also keen to see the exact “Dataset ID” property.
