Magento 2.2.6 : Shipment creation using REST API

Question

Unable to create shipment in Magento 2.2.6

I am using the following source code like this in postman

https://test.com/rest/V1/shipment

{ "entity" : { "order_id" : 70, "items" : [{ "order_item_id" : 94, "qty" : 1 } ], "tracks" : [{ "carrierCode" : "UPS", "order_id" : 70, "title" : "ground", "trackNumber" : "12345678", "parentId" : 1001 } ] } }

Thanks

Answer 1

It seems like your track array field format is wrong. Please try this below :

{  
   "entity":{  
      "order_id":70,
      "items":[  
         {  
            "order_item_id":94,
            "qty":1
         }
      ],
      "tracks":[  
         {  
            "carrier_code":"UPS",
            "order_id":70,
            "title":"ground",
            "track_number":"12345678",
            "parent_id":1001
         }
      ]
    ],
   }
}

UPDATE :

Go to this path /vendor/magento/framework/DB/Adapter/Pdo/Mysql.php and replace at line no 3036

case 'longtext':
    if (is_array($value)) {
        $value = json_encode($value);
    }
    $value  = (string)$value;
    if ($column['NULLABLE'] && $value == '') {
        $value = null;
    }
    break;
