wasm_wit_component generated code does not compile

[thejobsmarket]

Here is the wit file package mypackage:plugin

/// An example world for the component to target. world plugin { export widget-name: func() -> result<string, string> export widget-code: func() -> result<string, string> export request: func(key: string, config: string) -> result<string, string> }

Below is the fully generated file. However everywhere where there is a FuncType, e.g. const FuncType([], [('', ResultType(StringType(), StringType()))]), You get the following error: The element type 'String' can't be assigned to the list type '(String, ValType)'.
