Invalid part syntax

How parts are defined also defines how they behave.

An implementable part is defined by setting a name and a description. It should not have a path set. If you find yourself wanting to set a path, you probably want to do the following:

[ { "name": "part:foo/bar", "description": "Some really good description" }, { "implements": "part:foo/bar", "path": "./some/part.js" } ]

A non-overridable part can be defined by setting a name and a path in the same declaration:

{ "name": "part:@sanity/base/schema", "path": "./some/schema.js" }
