Struggling to validate a response against a JSON schema? Even if the schema is valid, it always seems to fail. Let's take a look at the JSON data and the validation code in Postman:
{
"items": [
{
"uuid": "f68ad4ba-a11e-485d-a2d7-17b9b07bd8d3",
"name": "Code",
"type": "app_code",
"description": "Code 1",
"content_type": "application/javascript",
"audit": {
"created_date": "2017-11-02T00:16:58.000Z",
"created_by": "e7c97dc1-08eb-45ef-b883-d100553bac5c"
}
},
...
],
"metadata": {
"total": 124,
"count": 3
},
"links": [
...
]
}
To validate this data, this code snippet is used in Postman:
const objectSchema = {
"items": [
...
],
"links": [
...
],
"metadata": {}
};
pm.test("JSON schema validation", function() {
var responseData = JSON.parse(responseBody);
var result = tv4.validate(responseData, objectSchema, false, true);
if (result !== true) {
console.log('Schema validation failed:', tv4.error);
}
pm.expect(result).to.be.true;
console.log(JSON.stringify(result));
});
If you encounter an error message like "Unknown property (not in schema)" in the console, how can you get more detailed information about what's causing the error? Any tips or solutions would be greatly appreciated!
