find a potential issue while writing unit test for wrap function call here both at browser and node side.

When input.Component is unset, got an error TypeError: subapp_1.envHooks.getContainer(...).get(...)._getExport is not a function
It’s because wrapper component will be gotten through subAppContainer when input.Component is undefined.
Since _getExport function is not required in Typescript declaration, it can be missing. So even we have question mark after that function call _getExported()?, but because it’s undefined, error will be throwed.
Another case is, if getExported is not a function, it will throw an error as well.

So I added several lines above to avoid the error. It simply console.error error msg and returns an component with error message.

good catch. it's not needed though.
_getExport is an internal function that the subapp2 engine guarantee to add when user declareSubApp. That's why it has the leading _.
when unit test manually create subapp def for mocking test, it should supply the _getExport if it's needed.
it should return a mock subapp module that has the Component
