# Description Fix #10506 by adding `ExpectedNonNull` `ShellError` if required field is entered as `$nothing`, `null`, " ", etc. This adds a new `ShellError`, `ExpectedNonNull`, taking the expected type and span. # User-Facing Changes Will get a more helpful error in the case described by #10506. Examples: ```nushell ➜ {scheme: "", host: "github.com"} | url join Error: nu:🐚:expected_non_null × Expected string found null. ╭─[entry #16:1:1] 1 │ {scheme: "", host: "github.com"} | url join · ─┬ · ╰── expected string, found null ╰──── ``` ```nushell ❯ {scheme: "https", host: null} | url join Error: nu:🐚:expected_non_null × Expected string found null. ╭─[entry #19:1:1] 1 │ {scheme: "https", host: null} | url join · ──┬─ · ╰── expected string, found null ╰──── ``` # Tests + Formatting All pass. |

Nushell core libraries and plugins
These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.
Foundational libraries are split into two kinds of crates:
- Core crates - those crates that work together to build the Nushell language engine
- Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.
Plugins are likewise also split into two types:
- Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
- Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
