invalid auth_type

Error message

invalid auth_type

What it means

Thrown by Yunpan360 Init()'s switch default when d.authMode() returns something other than "api_key" or "cookie". In the current code this is effectively unreachable: Init lowercases and defaults an empty AuthType to cookie, and authMode() returns api_key only when AuthType=="api_key", cookie otherwise. It is a defensive guard against future auth modes or a corrupted AuthType value (e.g. injected mid-struct without going through Init normalization).

Solutions

1. Set auth_type to exactly "cookie" or "api_key" (the values in meta.go options) and re-init
2. If constructing the driver in code, go through Init() so empty/odd values get normalized
3. On a fork adding a new auth mode, add the matching case to this switch

t := strings.ToLower(strings.TrimSpace(cfg.AuthType))
if t != "" && t != "cookie" && t != "api_key" {
    return fmt.Errorf("auth_type must be cookie or api_key, got %q", cfg.AuthType)
}

When it happens

Trigger: Calling driver methods on a Yunpan360 instance whose AuthType was set directly to an unrecognized value without running Init(); a future driver version adds a third auth mode but this switch wasn't updated.

Common situations: Programmatic use of the driver outside AList's config flow; hand-crafted driver structs in tests; merged configs from a forked driver exposing extra auth types.
