[BUG] Text '' could not be parsed at index 0 #435
Description
Environment
Java 1.4.0
Describe the bug
I'm using the FBA Inbound API getInventorySummary which returns a List of Items. Items have a lastUpdatedTime property which usually is a DateTime String but sometimes it's an empty string. Given this situation software.amazon.spapi.JSON.().getGson().fromJson(reader, software.amazon.spapi.models.fba.inventory.v1.GetInventorySummariesResponse.class) throws an Exception "Text '' could not be parsed at index 0". This bug has been reported previously here: amzn/selling-partner-api-models#291
To Reproduce
Try to deserialize the following JSON with software.amazon.spapi.JSON.().getGson().fromJson(reader, software.amazon.spapi.models.fba.inventory.v1.GetInventorySummariesResponse.class).
{
"pagination": {
"nextToken": "xxxx"
},
"payload": {
"granularity": {
"granularityType": "Marketplace",
"granularityId": "A1PA6795UKMFR9"
},
"inventorySummaries": [
{
"asin": "3831906734",
"fnSku": "yyy",
"sellerSku": "xxx",
"condition": "UsedVeryGood",
"inventoryDetails": {
"fulfillableQuantity": 0,
"inboundWorkingQuantity": 0,
"inboundShippedQuantity": 0,
"inboundReceivingQuantity": 0,
"reservedQuantity": {
"totalReservedQuantity": 0,
"pendingCustomerOrderQuantity": 0,
"pendingTransshipmentQuantity": 0,
"fcProcessingQuantity": 0
},
"researchingQuantity": {
"totalResearchingQuantity": 0,
"researchingQuantityBreakdown": []
},
"unfulfillableQuantity": {
"totalUnfulfillableQuantity": 0,
"customerDamagedQuantity": 0,
"warehouseDamagedQuantity": 0,
"distributorDamagedQuantity": 0,
"carrierDamagedQuantity": 0,
"defectiveQuantity": 0,
"expiredQuantity": 0
},
"futureSupplyQuantity": {
"reservedFutureSupplyQuantity": 0,
"futureSupplyBuyableQuantity": 0
}
},
"lastUpdatedTime": "",
"productName": "zzzz",
"totalQuantity": 0,
"stores": []
}
]
}
}See amzn/selling-partner-api-models#291
Expected behavior
An empty String should not fail but deserialize to null;
Additional context
The workaround from amzn/selling-partner-api-models#291 (comment) solves the issue.
