Issue with java.lang.ClassCastException: oracle.sql.StructDescriptor

Question

Hi ,
I'm creating a dbadapter for a custom API written in APPS schema -
TYPE MISIPM_LOB IS RECORD (
FILE_ID IPM_LOBS.FILE_ID%TYPE,
FILE_NAME IPM_LOBS.LOB_NAME%TYPE );
TYPE MISIPM_LOB_LIST IS TABLE OF MISIPM_LOB;
PROCEDURE GET_FILE_ID_DETAILS(
P_SOURCE_SYSTEM IN VARCHAR2,
p_entity_value IN VARCHAR2,
p_entity_code IN VARCHAR2,
P_ORG_ID IN NUMBER,
P_MISIPM_FILES_LIST OUT MISIPM_LOB_LIST,
P_ERRCODE OUT VARCHAR2,
P_ERRMESSAGE OUT VARCHAR2);
From JDeveloper, there is a wrapper package is getting created and the compilation/deployment of this composite is also without any error.
But when I run the composite, I'm surprisingly getting the below error -
Exception occured when binding was invoked. Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'GetAttachmentMetaData' failed due to: Interaction processing error. Error while processing the execution of the APPS.BPEL_GETATTACHMENTMETADATA1.XX_DELIVER_BLOB$GET_FILE_ API interaction. An error occurred while processing the interaction for invoking the APPS.BPEL_GETATTACHMENTMETADATA1.XX_DELIVER_BLOB$GET_FILE_ API. Cause: java.lang.ClassCastException: oracle.sql.StructDescriptor Check to ensure that the XML containing parameter data matches the parameter definitions in the XSD. This exception is considered not retriable, likely due to a modelling mistake. ". The invoked JCA adapter raised a resource exception. Please examine the above error message carefully to determine a resolution.
I recreated the adapter multiple times within the composite and also tried to create a separate composite and all the cases the error message received was same. There two more similar procedure call's in the composite and all rest of them are working fine.
I can call the wrapper from sql script separately.
Verified that the XSD generated and the wrapper package parameters are matching as well.
Did anyone face the same issue or any explanation/help is much appreciated.
