`ts-match` unable to infer types properly

I'm using the 
ts-match
 library to do some pattern matching on an object, and it seems unable to infer most types properly. Perhaps someone has experience with it.
My code is https://pastie.io/htxtti.ts and I'm seeing errors left, right, and center.

* 1: 
Type 'unknown' is not assignable to type '[typeString: string | undefined, skipImport: boolean]'

* 9: 
Object literal may only specify known properties, and 'enum' does not exist in type 'Matcher<never, unknown, any, any, unknown>'

* 10: 
Property 'enum' does not exist on type 'never'

* 10: 
Parameter 'e' implicitly has an 'any' type

* 13: 
Object literal may only specify known properties, and 'oneOf' does not exist in type 'Matcher<never, unknown, any, any, unknown>'

* 15: 
Property 'oneOf' does not exist on type 'never'

* 24: 
Object literal may only specify known properties, and 'properties' does not exist in type 'Matcher<never, unknown, any, any, unknown>

* 26: 
Property 'properties' does not exist on type 'never'

* 27: 
Argument of type 'unknown' is not assignable to parameter of type 'Type'

* 35: 
Object literal may only specify known properties, and 'type' does not exist in type 'Matcher<never, unknown, any, any, unknown>'

* 36: 
Property 'type' does not exist on type 'never'


For reference, the type I'm matching on is
export interface Type {
    type: string;
    enum?: string[] | undefined;
    format?: string | undefined;
    nullable?: boolean | undefined;
    properties?: Record<string, Type> | undefined;
    items: Type;
    oneOf?: Type[] | undefined;
    $ref?: string | undefined;
}
