471472`Invalid input` on a `source` means the object matched no source type. Check for these causes:
472473 
473* A relative path that doesn't start with `./`, other than `"."` or a [bare name under `metadata.pluginRoot`](#relative-path-plugin-source)
474474* An `npm` `package` containing `..`
475475* A `source` type that isn't one of the [plugin sources](#plugin-sources)
476476* A known type with a required field missing or of the wrong type, such as `github` without `repo`
477 
478A relative path that doesn't start with `./`, other than `"."` or a [bare name under `metadata.pluginRoot`](#relative-path-plugin-source), fails with `Invalid string: must start with "./"`. Before v2.1.285, it printed `Invalid input` like the causes above.
