JSON Array not passing in rest api

With EBS 12.2.10 and database 19c (19.10.0.0.0) I deploed a rest api with CLOB parameter in which passing a json array. Log file shows following details which indicates that parameter did not passed correctly:

<oracle.tip.adapter.db.sp.AbstractStoredProcedure execute> BEGIN APPS.XRCL_CB_INBOUND_TEST_PKG.TALLYQUANTITY(P_TRANSACTION_LINES=>?, X_RESPONSE_CODE=>?, X_RESPONSE_MESSAGE=>?); END;

<oracle.tip.adapter.db.sp.AbstractStoredProcedure execute> Bindings [P_TRANSACTION_LINES=>CLOB(<TRANSACTION_TYPE>IO</TRANSACTION_TYPE>), X_RESPONSE_CODE<=VARCHAR2, X_RESPONSE_MESSAGE<=VARCHAR2]

where P_TRANSACTION_LINES is json array parameter.

What may be the reason for this issue?
