Trying to trigger zoho com module from Zoho books invoice

We would like to have a module in our CRM that shows only certain purchases. In our case salt that customer purchase on a regular basis.

Introduced myself to flow and setup a rule that the invoice line item must be one of three things- Great.

Next create module entry into CRM using customer id from invoice going into crm lookup field, date, and then line item into a text field.

Firstly we got an error on CRM was not getting the correct data. Next on the flow we inserted fetch contact. The flow now runs but leaves the CRM contact lookup field empty.

Plus the text field shows all the line items details, everything. All we wanted was a the item name and quantity. Can this data be parsed to provide that?
