Problem with Zoho CRM and Zapier: Unable to create entry in module: Invoices. Required field not found / in_request_body false

Hello, 

I have created a Zap in Zapier that creates a new entry in the regular Invoices module. 

Today (and for some reasons…I do not why) I get an error message in Zapier: 
Hello, 

Unable to create entry in module: Invoices. Error : required field not found. Detail : api_name Product_Details, in_request_body false

I did not change anything in the Zap and all required data is added in this Zap. 

How can I solve this problem?

Thanks for help, 
Michael
