Trace doesn't show up in Google Cloud Logging Explorer

[canatufkansu]

Hi,

I have installed the package for all of the logs in my Laravel 7 project. There is only thing I couldn't figure out. In the Google Cloud Logging (GCL), I can see the logs but there is no trace information. Without the trace it is difficult to point to error in the project.

In logging.php in Laravel I have setup a new channel as follows

       'gcl' => [
            'driver' => 'custom',
            'via' => CodeInternetApplications\MonologStackdriver\Laravel\CreateStackdriverLogger::class,
            'logName' => 'Zeus_'.env('APP_ENV'),
        ],

and changed LOG_CHANNEL to 'gcl' in .env file.

In Logs Explorer in GCL, I see the log as follows

{
  "insertId": "1pw3ckdfpobou1",
  "jsonPayload": {
    "message": "Undefined offset: 4",
    "data": {
      "exception": {},
      "userId": 100014
    }
  },
  "resource": {
    "type": "global",
    "labels": {
      "project_id": "fizbot-v2"
    }
  },
  "timestamp": "2021-05-29T14:30:44.885308Z",
  "severity": "ERROR",
  "logName": "projects/fizbot-v2/logs/Zeus_local",
  "receiveTimestamp": "2021-05-29T14:30:45.324374997Z"
}

I was expecting to see the whole trace under data element in jsonPayload.

After I have added new lineFormat, I can see the last line of the trace in the GCL but not all of it and all of the data is in the message section

'gcl' => [
            'driver' => 'custom',
            'via' => CodeInternetApplications\MonologStackdriver\Laravel\CreateStackdriverLogger::class,
            'logName' => 'Zeus_'.env('APP_ENV'),
            'lineFormat' => '[%datetime%] %channel%.%level_name%: %message% %context% %extra%',
        ],

{
  "insertId": "l3chdjfl3i9ht",
  "jsonPayload": {
    "message": "[2021-05-29T14:36:17.221251+00:00] stackdriver.ERROR: Undefined offset: 4 {\"userId\":100014,\"exception\":\"[object] (ErrorException(code: 0): Undefined offset: 4 at /Users/canatufkansu/Sites/zeus/app/GraphQL/Queries/TestQuery.php:16)\"} []",
    "data": {
      "userId": 100014,
      "exception": {}
    }
  },
  "resource": {
    "type": "global",
    "labels": {
      "project_id": "fizbot-v2"
    }
  },
  "timestamp": "2021-05-29T14:36:17.221298Z",
  "severity": "ERROR",
  "logName": "projects/fizbot-v2/logs/Zeus_local",
  "receiveTimestamp": "2021-05-29T14:36:17.551372993Z"
}

I can live with this but is there better configuration that I can get the whole trace in Google Cloud Logging ?
