DigestFinal method throws ARGUMENTS_BAD error

[paulmgtech]

Hi

Got below Error:
Exception in thread "main" org.pkcs11.jacknji11.CKRException: 0x00000007: ARGUMENTS_BAD
at org.pkcs11.jacknji11.CE.DigestFinal(CE.java:1162)
at org.pkcs11.jacknji11.CE.DigestFinal(CE.java:1174)
at org.pkcs11.jacknji11.Test.main(Test.java:190)
C_DigestFinal failed with error CKR_ARGUMENTS_BAD : 0x00000007

When I run:
CE.DigestInit(session, new CKM(CKM.SHA256));
CE.DigestUpdate(session, new byte[50]);
CE.DigestUpdate(session, new byte[50]);
byte[] digested2 = CE.DigestFinal(session);

Can you help me out to fix this issue.
