'u' Replaced By 'U' Is A Big Error,Insight From My On Going Spring Boot Project
For Three days I was struck on running my Cart endpoints.Everything seems correct. But the Error on running the endpoint was : { "success" : false , "message" : "The given id must not be null" , "data" : null } Somewhere the ID was becoming null before it reaches the repository even when i was passing the Id. Project Explanation Let me first clear the endpoints and scenario to you. I am Building…
For three days, the reporter faced an issue while running their Cart endpoints in their Spring Boot AI-powered e-commerce project. Despite everything appearing correct, the endpoint returned an error: { success : false, message : "The given id must not be null", data : null }. The reporter was puzzled, as they were passing IDs to the endpoint.
The project involved building a full-fledged AI-assisted e-commerce platform using Spring Boot, OpenAI Models, and BLIP-CLIP models for image-to-text and text-to-image processing. The reporter was focusing on creating entities, repositories, services, and controllers for the website's basic functionality, along with using DTOs for structured data transfer.
Upon further investigation, the reporter discovered the error was due to a capitalization discrepancy in their DTO variables. Specifically, the JSON property names did not match the Java class variable names, causing the JSON data to be mapped to null values. The reporter learned that adhering to conventions and ensuring JSON property names match Java class variable names exactly is crucial for proper data binding and error-free development.
