Error description

  • When you invoke an IBM Business Process Manager (BPM) REST API
    by using a JSON object as an input parameter for a data object,
    such as to change variable values, you might get the following
    error:
    
    "CWTBG0029E: The parameter 'params' has an unsupported value".
    
    The error occurs when the JSON object passed in represents a
    complex business object from the system toolkit. The error
    appears in the API Response message and in an FFDC log entry.
    
    The following list refers to all the IBM BPM REST calls that
    might be affected:
    
    Process Resource - Start Method (Start Process)

    _setdata.htm?cp=SSFPJS_7.5.1&lang=en
    
    The following list refers to the complex business objects from
    the system toolkit that might cause the issue:
    NameValuePair
    ConditionalActivity
    CaseReference
    IndexedMap
    SLAViolationRecord
    SQLDatabaseType
    SQLParameter
    SQLResult
    SQLResultSetColumn
    SQLStatement
    TWHolidaySchedule
    TWTimePeriod
    TWTimeSchedule
    TWWorkSchedule
    
    The same underlying problem addressed by this APAR might cause
    an error in Process Inspector in Process Admin Console as well.
    Trying to change the value of variables, the Process Inspector
    might show an error box in the UI starting with the error
    information: "javax.servlet.ServletException:
    com.ibm.processinspector.rest.ProcessAdminRestException: Error
    changing values".
