FAILURE: Build failed with an exception.

Is there anything else we need to know about?

No response

Hi, you also need to add the KSP dependency for JS.

add("kspJs", libs.ktorFitKsp.get())

I spent way too long on this error, for anyone also experiencing this. This error can also occur if you accidentally create an empty interfaces. i.e.

interface A {}

ktorfit.create<A>()
