How to fix the error 'API call to bigquery.jobs.query failed with error: Encountered " "FROM" "from "" at .... Was expecting: ")"' - google-apps-script

Question

I am trying to run a bigquery api call using the query string(attached in the code) from appscript; The query runs perfectly fine in bigquery UI
I have tried the following with no success:
1. include parentheses in orders.creation_date in the query string
2. replace orders with the actual table table i.e [my-project:theservices.theservice_order_item]
/**
* Runs a BigQuery query and logs the results in a spreadsheet.
*/
function runQuery() {
var projectId = 'my-project';
var request = {
query:
"SELECT extract(date from orders.creation_date) as the_date \n FROM [my-project:theservices.theservice_order_item] AS orders LIMIT 10;"
};
};
Following is the error I get:
API call to bigquery.jobs.query failed with error: Encountered " "FROM" "from "" at line 1, column 22. Was expecting: ")" ... (line 23, file "Code")

Quoting App Script BigQuery Standard SQL insert or update statement:
You need to set the useLegacySql flag/parameter to false, to indicate that you want to use standard SQL, like so:
var job = {
configuration: {
query: {
query: 'SELECT ....',
useLegacySql: false
}
Additionally, when a table looks like this - that's #legacySQL:
FROM [my-project:theservices.theservice_order_item]
In #standardSQL the table should be enclosed in tilde '`' and has a '.' between the project and dataset name:
FROM `my-project.theservices.theservice_order_item`
