Data Studio Community Connector for Bigquery - advanced-services - google-apps-script

Question

I am customizing an advanced service community connector. In this case to keep it simple I omit the parameters and do a query.
I follow the following example:
Advanced Services de Data Studio
I checked the getData () method for better documentation:
A JavaScript object representing the BigQuery query configuration.
I checked the Data Studio advanced service example repository for the most complete example:
getData(request)
Manifest : "useQueryConfig": true
The code is as follows (a simple query):
<code>var sqlString = ' SELECT name FROM `xxxx-101010.xxxx.xxxxxx` ';
function getAuthType() {
var cc = DataStudioApp.createCommunityConnector();
return cc.newAuthTypeResponse()
.setAuthType(cc.AuthType.NONE)
.build();
}
function getConfig(request) {
var cc = DataStudioApp.createCommunityConnector();
var config = cc.getConfig();
return config.build();
}
function getFields(request) {
var cc = DataStudioApp.createCommunityConnector();
var fields = cc.getFields();
var types = cc.FieldType;
fields.newDimension()
.setId('newDimensionName')
.setName('Package')
.setType(types.TEXT);
return fields;
}
function getSchema(request) {
return {schema: getFields().build()};
}
function getData(request) {
var authToken = ScriptApp.getOAuthToken();
var bqConfig = DataStudioApp.createCommunityConnector().newBigQueryConfig()
.setAccessToken(authToken)
.setUseStandardSql(true)
.setQuery(sqlString)
.build();
return bqConfig
}
</code>
The query I have tried with a table created by me (Permission: BigQuery data owner) and a public table (Permissions by default).
