Zoho books not accepting valid state code via api

Hello, I am using make.com to create a contact and then invoice for a Shopify orders. However, while creating contact I'm getting "please provide a valid state code" error even though I'm providing correct state code. For example I'm providing MH as state code for Maharashatra still getting the same error. Please find the attached error and input screenshots.
