Hi

Does someone know how to work properly with putdynamodb?

I'm getting this error  "Hash key value '' is required for flow

My flow is the next

The configuration of my processor is the next

My Partition Key in the dynamo table is Recursos ID

my json is the next

{
    "id"1,
    "nombres":"Gian",
    "paterno":"Perez",
    "materno":"Perez",
    "rfc":"PEPJ870530N11",
    "domicilios":[
        {"calle":"calle 10","colonia":"Miraflores","cp":"0000"}
    ]
}
 
Thanks in advance

@CJ-Llanes ,

 

The expression ${id} refers to a flowfile attribute called "id", not to the "id" attribute of your flowfile content.

You need to extract the "id" from the flowfile first with a EvaluateJsonPath between your FlattenJson and PutDynamoDB processors. Like this:
