PHP BigQuery Client Error Code: 401 running long job - php

Question

I got a PHP BigQueryClient that I use to export big tables to csv from BQ, but after running for a while they throw and error with code 401:
Google\Cloud\Core\Exception\ServiceException
{
"error": {
"code": 401,
"message": "Request had invalid authentication credentials. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
"errors": [
{
"message": "Invalid Credentials",
"domain": "global",
"reason": "authError",
"location": "Authorization",
"locationType": "header"
}
],
"status": "UNAUTHENTICATED"
}
}
it occurs when running a long while that goes over the rows of the table like this
$bigQuery = new BigQueryClient([
'keyFile' => $array[$key],
'projectId' => $this->projectId
]);
//This is to get total row count so we can loop over it
$info = $bigQuery->dataset($this->datasetId)->table($tableName)->info();
//Output row count, and status message
$this->info($this->messagePrepend . "Rows: " . number_format($info['numRows']) . ", Chunk size: " . number_format($this->chunkSize) . " – Processing.." . PHP_EOL);
$startTime = Carbon::now();
//Open our output file
$file = fopen(storage_path("tmp/{$tableName}.csv"), 'w');
fputcsv($file, $this->tableHeaders);
$orderBy = match ($keyword) {
default => "id"
};
while ($info['numRows'] > $offset) {
$config = $bigQuery->query("SELECT * FROM {$this->datasetId}.{$tableName} ORDER BY {$orderBy} ASC LIMIT {$this->chunkSize} OFFSET {$offset}");
$job = $bigQuery->startQuery($config);
$queryResults = collect($job->queryResults());
$queryResults->map(function ($row) {
$line = [FORM LINE]
fputcsv($file, $line);
});
$offset += $this->chunkSize;
}
I've tried looking for the causes for this, and it seems like the issue is that the client token expires after an hour.
Despite that I've not found a way to refresh it, cause it doesn't seem to do so automatically, could anyone help me figure out how to do that?
I've read cloud bigquery docs but they didn't provide me with much answers, and neither did google

Resolved it by updating the instance of BigQueryClient when an exception is thrown:
try {
$job = $bigQuery->startQuery($config);
} catch (\Throwable $th) {
$this->warn("Code: " . $th->getCode() . ": " . $th->getMessage(), 'vvv');
$bigQuery = new BigQueryClient([
'keyFile' => $array[$key],
'projectId' => $this->projectId
]);
$job = $bigQuery->startQuery($config);
}
