  • 1.  Java SDK 236.0.0 - Jackson Deserialization Error on ContractDefinition class for Decision Tables

    Posted 11-18-2025 02:31

    SDK Version: 236.0.0

    Java Version: 21.0.9

    Spring Boot Version: 3.5.7

    Description:

    I'm trying to implement a service that retrieves Decision Table information.

    When I call the 

    BusinessRulesAPi.getBusinessrulesDecisiontable(GetBusinessrulesDecisiontableRequest)

    method from the SDK I'm finally ending up with a Jackons error:

    com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of `java.util.ArrayList` (although at least one Creator exists): no String-argument constructor/factory method to deserialize from String value ('string')
     at [Source: REDACTED (`StreamReadFeature.INCLUDE_SOURCE_IN_LOCATION` disabled); line: 1, column: 9057] (through reference chain: com.mypurecloud.sdk.v2.model.DecisionTable["publishedContract"]->com.mypurecloud.sdk.v2.model.DecisionTableContract["rowAuthoringSchema"]->com.mypurecloud.sdk.v2.model.ContractJsonSchema["definitions"]->java.util.LinkedHashMap["string"]->com.mypurecloud.sdk.v2.model.ContractDefinition["type"])

    A debugging session reveals that the error occurs in the method 

    _deserializeFromString

    in the Jackson class StdDeserializer.

    This happens when trying to deserialize the "string" definition in the "rowAuthoringSchema" -> "definitions" object:

    I've seen a similar error message from Jackson when updating from 2.17.2 to 2.18+.

    While coding the request to get the Decision Table Rows I noticed that in the 

    com.mypurecloud.sdk.v2.api.request.GetBusinessrulesDecisiontableVersionRowsRequest

    class the "pageNumber" and "pageSize" are defined as String which doesn't really make sense.

    If you look at the 

    GetFlowsDatatableRowsRequest

    the pageNumber and pageSize are defined as "Integer".

    Hello,

    • Regarding your first question/problem - the deserialization error - it appears to be a problem in the API Endpoint contract.

    See my response to Zlotan in this other post: https://community.genesys.com/discussion/conflict-between-platform-sdk-and-api

    No need to create a ticket if Zlotan shares his existing Customer Care ticket number (so I can reach out to engineering and communicate it to them).

    • Regarding your second question: pageNumber and pageSize declared as string

    This is defined this way in the API Endpoint contract (and as explained in the other post, the SDKs are automatically generated out of the Platform API Open API v2.0/Swagger definition). And you are right, it should be defined as an integer to be consistent with other endpoints.

    Could you please open a ticket with Customer Care to report this issue? And share the ticket number here.

    Once I have it, I'll reach out to engineering to let them know about the issue. (you can reference this post/my answer, in your exchange with Customer Care).

    Thank you.

    Regards,
