The errors you're seeing there are very nice, and I think highlight a real problem when the current user is anonymous. You should be able to narrow the type by checking for properties that are only present for non-anonymous users.

Love this - I would say dropping rethrowSimple will mean that the standardized error messages produced on the backend are going to be suppressed and not included to upstream components so I'd prefer to see hooking into the existing error handling stuff but I understand the desire for simplicity also.

Fetcher has a rethrowSimple middleware,

galaxy/client/src/schema/fetcher.ts

Line 9 in d15b2fe

const rethrowSimpleMiddleware: Middleware = async (url, init, next) => {

so this isn't needed
