How to return error messages to client?

[awatson1978]

Hello,
Neither a bug nor a feature request (yet), just trying to figure out the recommended approach to returning an error message to the client.

When I try to log in using an incorrect password, I can generate an AccountsJsError easily enough, and I see the Invalid credentials message in the server console.

However, when I try to catch the error on the client, I'm getting a TypeError, because the accounts/password/authenticate endpoint isn't returning a proper payload.

Here is my code.

Should I be using a specific HTTP message code? Does the error get put into the body of the response? In the header? Something else?

Any guidance on how to wire this up correctly would be much appreciated!

What you could do for this:

• in your catch clause server-side replace the code property of the payload to the corresponding code property in the error object.
• in the client side do not check the AccountsError type but respect a JSON object with a code property.
