Logic Apps - When an HTTP request is received > Intialize variable

Question

Hi,

I am struggling to initialise variables from the JSON response triggerbody. they return as null.

(1) When a HTTP Request is received (GET)

with JSON Schema:
{
"properties": {
"WorkType": {
"type": "string"
}
},
"type": "object"
}

(2) Initialize a variable..

        "Initialize_variable": {  
            "inputs": {  
                "variables": [  
                    {  
                        "name": "Test",  
                        "type": "string",  
                        "value": "@triggerBody()?['WorkType']"  
                    }  
                ]  
            },  

Output is null

I am sending objects by appending parameters in the JSON Schema to the url as below
https://azureprod?api-version=2016-10-01&sp=%2Ftriggers%2Fmanual%2Frun&sv=1.0
&sig=sigkey
&WorkType=Personalproject
&Urgency=3
etc..

I need to extract several values from the JSON in this manner, performing a few functions and then packaging a response.

Thank you very much for your help as I am stumped

Hi @hbaw ,

Welcome to Microsoft Q&A Platform. Thank you for the question.

I would suggest to initialize the variable and then set the variable like below screenshot. And you have the JSON schema so you can add the fields and can use for several values.
