Solution

  • The issue is on the prerequest script (Cannot read properties of undefined (reading "name")), so the issue is on this line

    pm.collectionVariables.set("name", data["profile"]["name"]);

    which means that data["profile"] is undefined. Looking at the mapping of data.json, the correct syntax should be data[0]["profile"]["name"], as data is an array of objects.
