[Solved] You have this response mapping template:{ "message": "$input.path('$.msg')", "status": "$input.path('$.code')" }But the backend returns:{"message": "Success", "code":... | AWS

AWS - API Gateway

You have this response mapping template:

{
  "message": "$input.path('$.msg')",
  "status": "$input.path('$.code')"
}

But the backend returns:

{"message": "Success", "code": 200}

What is the main issue causing the mapping to fail?

AThe template uses wrong JSON paths not matching backend keys

BThe backend response is not valid JSON

CThe template syntax is missing quotes around keys

DThe backend response keys are case-insensitive

Step-by-Step Solution

Solution:

Step 1: Compare template paths with backend keys
The template expects msg and code, but backend returns message and code.
Step 2: Identify mismatch causing failure
Since msg does not exist in backend response, mapping fails for that field.
Final Answer:
The template uses wrong JSON paths not matching backend keys -> Option A
