Compiler: 'Too Many Arguments' Error Despite Providing Necessary Input

When attempting to use a struct as a parameter for the JSON() function, you may encounter a "too many arguments" error despite providing all required inputs. This issue arises when the syntax for struct initialization is incorrect, causing the compiler to throw the error.

To resolve this error, ensure that curly braces {} are used for struct initialization. For example, the following syntax is incorrect:

resp := DataResponse(200, user)

Instead, use the following correct syntax:

resp := DataResponse{200, user}

By adding the curly braces, you correctly initialize the struct with the two required parameters: Status and Data. The Data parameter accepts an interface type, so it can accommodate the models.User datatype.

Now, the compiler will recognize the correct syntax, and the error message will no longer appear.
