Sensor and data stream modules do not check payload data validity #716
Description
Describe the bug
Saw a few errors on one of the instances I host. Seems like invalid data was being sent to a sensor, and farmOS code doesn't check for that. These are the two specific errors I saw, one in the farm_sensor module and one in the data_stream module:
TypeError: Drupal\farm_sensor\Controller\SensorDataController::getUniqueNamedValues(): Argument #1 ($data) must be of type array, null given, called in /opt/drupal/web/profiles/farm/modules/asset/sensor/src/Controller/SensorDataController.php on line 138 in Drupal\farm_sensor\Controller\SensorDataController->getUniqueNamedValues() (line 186 of /opt/drupal/web/profiles/farm/modules/asset/sensor/src/Controller/SensorDataController.php)
TypeError: Drupal\data_stream\Plugin\DataStream\DataStreamType\Basic::storageSave(): Argument #2 ($data) must be of type array, null given, called in /opt/drupal/web/profiles/farm/modules/core/data_stream/src/Plugin/DataStream/DataStreamType/Basic.php on line 320 in Drupal\data_stream\Plugin\DataStream\DataStreamType\Basic->storageSave() (line 422 of /opt/drupal/web/profiles/farm/modules/core/data_stream/src/Plugin/DataStream/DataStreamType/Basic.php)
To Reproduce
TBD
Expected behavior
farmOS should return a 422 Unprocessable Content response.
