GLS trackPackages return empty statuses

[eugeene]

Detailed description

When tracking GLS packages, statuses returned by trackPackages() are always empty.

Possible implementation

the issue is due to this part of code:

    if (empty($response[0])) {
        throw new BadRequestException($response);
    }

$response[0] can be empty and thus will throw an exception, crude (don't now if good) solution is to check $response[1] being set:

    if (empty($response[0])) {
		if(empty($response[1])) {
			throw new BadRequestException($response);
		}

		$response[0] = $response[1];
    }

There is problem with response data from API. For GLS shipper TRACK request API returns only last package statuses. In your case, there are data only for second package with index [1].

Method doesn't throw exception now (fixed in v3.1.0, it returns empty array for missing indexes instead.

The response data for multiple packages for other shippers are correct. Response from TRACK_STATUS request for GLS shipper with multiple packages is also correct.

I recommend contacting Balikobot support to resolve this issue.
