I got this same error. (Details: org.hibernate.id.IdentifierGenerationException: ids for this class must be manually assigned before calling save())

I had wanted to create my first Appian WEB API.

I created a Data Store Entity without an autogenerated ID field.

I created a Service Account and got an API key, put the Service account into the viewer group and gave it access to my DSE, per the docs (Creating Web APIs - Appian 21.3)

My primary key(PK) field is unique, and called CNUMBER.

I tried to use the first example example in the

a!writeToDataStoreEntity(
  dataStoreEntity: cons!CES_POINTER_CHECKS_DATASTOREENTITY,
  valueToStore: type!Employee(
    CNUMBER: http!request.queryParameters.CNUMBER,
    CDATE: http!request.queryParameters.CDATE,
    CAMOUNT: http!request.queryParameters.CAMOUNT,
    CDESC: http!request.queryParameters.CDESC
  ),
  onSuccess: a!httpResponse(
    statusCode: 200,
    headers: {
      a!httpHeader(name: "Content-Type", value: "application/json")
    },
    body: a!toJson(
      fv!storedValues
    )
  ),
  onError: a!httpResponse(
    statusCode: 500,
    headers: {
      a!httpHeader(name: "Content-Type", value: "application/json")
    },
    body: a!toJson(
      {
        error: "There was an error writing to the data store"
      }
    )
  )
)

When I tested it in the WEB API node it worked perfectly and added or updated a record in my table.

When I tried to access remotely, I got the error.

I tried adding an auto generated id field, then the WEB API node failed and I still got the error. I would up fixing this by using the Web API Tutorial Level II example: Web API Tutorial - Level II - Appian 21.3

So the working code is:

a!localVariables(
local!value: cast(
'type!{urn:com:appian:types}CES_CHECKS',
a!fromJson(http!request.body)
),
a!writeToDataStoreEntity(
dataStoreEntity: cons!CES_POINTER_CHECKS_DATASTOREENTITY,
valueToStore: local!value,
onSuccess: a!httpResponse(
statusCode: 200,
headers: {
a!httpHeader(
name: "Content-Type",
value: "application/json"
)
},
body: a!toJson(fv!storedValues)
),
onError: a!httpResponse(
statusCode: 500,
headers: {
a!httpHeader(
name: "Content-Type",
value: "application/json"
)
},
body: a!toJson(
{
error: "There was another error writing to the data store"
}
)
)
)

)

Which works great when called from UBUNTU curl as follows:

curl myenv.appian.community/.../myenv_cendpoint -H "Appian-API-Key:MySecretApiKeykjldsjfksjflsjdfsjldsjfkldjslfj" -H "Content-Type:application/json" --request POST --data '{"CNUMBER":12,"CDATE":"20210920","CAMOUNT":2123.44,"CDESC":"a desc"}'

This was a pain to hack out. Hope this helps someone!

The comment from sayalip helped me in my case. For some reason the "@GeneratedValue" wasn't added to the primary key field in the XSD by Appian, so I added this manually and the error was resolved.

Hi,

Please download your XSD and add JPA annotations appropriate to your requirement (add @GeneratedValue for your ID field), save it and then create a new version of the CDT from XSD. You will need to verify and publish your Data Store again in order to reflect these changes.

Hope it helps!!

Please check the primary key in the CDT and see if the auto-generate option is selected, else you will have to pass a value to the PK before writing records to a data store entity.

Hi,

We are providing all the primary keys through the process. Still its giving this error.
