I’m new to postman flows and I need a help from you guys, I’m trying to pass the data from one block to another, the first block is successfully sending the data but the problem is within the second block it is not capturing the data correctly, i will provide you the whole flow in a picture below you can find it.enter image description here

The pass data is the value of body.responseBody from the first block which is a String “RANDOM12Aw” and it’s need to be pass as a request param of the second block. I will provide the second block API as well in the form of picture, please check it once.
enter image description here

if you see the picture 2 it is the API for the block 2 and in the place of key i leave it blank cause it need to get the value form the block1. The problem here is the key is empty. The data is not retrieving properly,

Expecting a proper solution or the suggestions that can solve my problem.
