Can't handle the response of subform fields?

Can't handle the response of subform fields?

I have created the flow for create contact in Books when New record is created in Zoho Creator. When mapping the fields for Books contacts, I can't find some subform fields and also I can't parse the response of the subform field( e.g. [{Added_Location=, contact_account=Only Test Cuber, title=, Modified_User_IP_Address=157.50.245.248, primary_contact_for_accounts=false, Delivery_Contact=false, internal_client_id=6002122438, vendor=false, mobile_phone=, delivery_setup=, Added_User=zoho_frank1111, ID=3332934000008038792, main_phone=, email=, delivery_contact=, Added_Time=15-Jul-2019 06:08:38, Modified_User=zoho_frank1111, contact_name=Jay K, Modified_Time=15-Jul-2019 06:08:38, Modified_Location=, accounts_crm_id=, Section=, Added_User_IP_Address=157.50.245.248, internal_crm_id=, phone=, Billing_Contact=false, books_contact_person_id=, primary_contact=true}, {Added_Location=, contact_account=Only Test Cuber, title=, Modified_User_IP_Address=157.50.245.248, primary_contact_for_accounts=false, Delivery_Contact=false, internal_client_id=6002122438, vendor=false, mobile_phone=, delivery_setup=, Added_User=zoho_frank1111, ID=3332934000008038796, main_phone=, email=, delivery_contact=, Added_Time=15-Jul-2019 06:08:38, Modified_User=zoho_frank1111, contact_name=janu Khan, Modified_Time=15-Jul-2019 06:08:38, Modified_Location=, accounts_crm_id=, Section=, Added_User_IP_Address=157.50.245.248, internal_crm_id=, phone=, Billing_Contact=false, books_contact_person_id=, primary_contact=true}] ) How can I get the "contact_name" from this response?
