POSTMAN : TypeError: cannot read properties of undefined (reading ‘Json’)

Question

Body of output: I am taking the token response from body and passing it to variable called "Token"

{
    "message": "Success",
    "data": {
        "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.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.NS9nl4_3C9vsmogWntMXlg44E_pBhoL3oFryvl0wKsg"
    }
}

This is the test script:

{{
   var responseBody= pm.responseBody.json();
   pm.collectionVariables.get(responseBody.data.token);
   console.log(responseBody.data.token);`
}}

Problem : test result is failing showing Type Error: cannot read properties of undefined (reading ‘Json’).

Answer 1

Try this. Looks like you're using .responseBody where it should just be .response:

var responseBody = pm.response.json();
