PutDynamoDB Error - Hash Key Value

[#1]

Hello, Everyone!

I have been trying to use the PutDynamoDB processor, and I almost there. I'm able to run the ExecuteSQLRecord to get my data and store in a JSON file. The data is flowing, but I'm getting the following error in the log:

PutDynamoDB[id=28e4e8cf-016b-1000-a35c-276514f81580] Hash key value '' is required for flow file StandardFlowFileRecord[uuid=0ce692ff-d784-4882-a565-f5425479d316,claim=StandardContentClaim [resourceClaim=StandardResourceClaim[id=1559758360111-4, container=default, section=4], offset=0, length=275868738],offset=0,name=0ce692ff-d784-4882-a565-f5425479d316.json,size=275868738]

I understand that, is looking for the Hash Key Value, but I not sure how do I pass it. In the PutDynamoDB properties tab, NiFi sets

${dynamodb.item.hash.key.value} 

as default value. But looks like this isn't the right way to do it.

Can I get some guidance on this?

My workflow:

The JSON I'm trying to put in DynamoDB looks like this:

1. [ {
2.   "CUSTOMER_ID" : "11111111111",
3.   "TRANSACTION_TYPE" : "G",
4.   "ID_TRANSACTION" : 3,
5.   "ACCOUNT_ID" : 111111111,
6.   "TRANSACTION_VALUE" : "100.00"
7. }, {
8.   "CUSTOMER_ID" : "22222222222",
9.   "TRANSACTION_TYPE" : "G",
10.   "ID_TRANSACTION" : 10,
11.   "ACCOUNT_ID" : 222222222,
12.   "TRANSACTION_VALUE" : "1000.00"
13. }, {
14.   "CUSTOMER_ID" : "33333333333",
15.   "TRANSACTION_TYPE" : "R",
16.   "ID_TRANSACTION" : 8,
17.   "ACCOUNT_ID" : 333333333,
18.   "TRANSACTION_VALUE" : "3000.00"
19. }
20.  ]

Any help will be appreciated

Thanks!
