Rest API - Error Handling

You want to design a nested error response for a REST API that validates a user profile with nested address fields. Which JSON structure best represents errors for both the email and nested address.zipcode fields?

A{ "error": { "email": "Invalid", "address.zipcode": "Missing" } }

B{ "error": { "fields": { "email": "Invalid", "address": { "zipcode": "Missing" } } } }

C{ "error": [ { "email": "Invalid" }, { "address": { "zipcode": "Missing" } } ] }

D{ "error": "Invalid email and missing zipcode" }

Step-by-Step Solution

Solution:

Step 1: Understand nested error reporting for nested fields
Nested fields like address.zipcode should be represented as nested objects.
Step 2: Evaluate JSON options for nested structure
{ "error": { "fields": { "email": "Invalid", "address": { "zipcode": "Missing" } } } } uses a 'fields' object with 'email' error and nested 'address' object containing 'zipcode' error.
Final Answer:
{ "error": { "fields": { "email": "Invalid", "address": { "zipcode": "Missing" } } } } -> Option B
Quick Check:
Nested fields use nested objects = { "error": { "fields": { "email": "Invalid", "address": { "zipcode": "Missing" } } } } [OK]

Quick Trick: Use nested objects for nested field errors [OK]

Common Mistakes:

Using dot notation keys instead of nested objects
Flattening nested errors into arrays
Combining all errors into one string
