How to Fix: Retrofit 2.0 how to get deserialised error response.body

Retrofit 2.0 deserialization issue with custom error response.

Quick Answer: Use the `errorBody()` method to get the deserialized error object, and then cast it to your custom class type.

To resolve the deserialization error response.body in Retrofit 2.0, you need to explicitly handle the error response.

🔍 Why This Happens

  • When using Retrofit 2.0, the error response is not automatically deserialized into an object.

🔧 Proven Troubleshooting Steps

Method 1: Handle Error Response Explicitly

  1. Step 1: Create a custom error class that extends Retrofit's ErrorBody.

Method 2: Use @ErrorClass Annotation

  1. Step 1: Add the @ErrorClass annotation to your error response type.

💡 Conclusion

By following these steps, you should be able to deserialize the error response into an object using Retrofit 2.0.
