BigQuery php client library queryresult shows isComplete false. But I can confirm the query is successful - google-bigquery

Question

$queryResults = $this->bigQuery->runQuery($query, ['parameters' => ['id' => $id]]);
$info = $queryResults->info();
var_dump($info);
// var_dump($queryResults);
$isComplete = $queryResults->isComplete();
if ($isComplete) {
exit("Insert. Done!");
}
The query is a "insert select" statement. which I had run successful on bigquery cloud console directly.
When I use php client library here, the query finished successful too and I can confirm that it is the same as I run query directly on google cloud console.
But the info of the query shows isComplete false.
array(3) {
["kind"]=>
string(22) "bigquery#queryResponse"
["jobReference"]=>
array(2) {
["projectId"]=>
string(26) "myprojectid"
["jobId"]=>
string(31) "job_OHcckVSSwAI7pHXijmmUqK5H4XE"
}
["jobComplete"]=>
bool(false)
}
There are no errors report form the $queryResults->info();. How could I find out why it shows me isComplete false?

Probably you still need to run $queryResults -> reload() to update the job status. As in the docs:
$isComplete = $queryResults->isComplete();
while (!$isComplete) {
sleep(1); // small delay between requests
$queryResults->reload();
$isComplete = $queryResults->isComplete();
}
