"error occured in dts build" without any other details

[IanVS]

Hi, I am getting error occured in dts build, but there are no other details about the error, or why it is occurring. It happens when I change a type in one of my types.ts files from an express Router to a fastify FastifyInstance, but I have no idea why. I see where the error is being created in dtsTask, but is it possible to add some extra debugging information to help troubleshoot why I have a failure?

I was able to get some details about the error by tweaking tsup in node_modules

- logger.error("dts", "Build error");
+ logger.error("dts", error.message);

which gave me something I could dig into:

'FastifyError' is not exported by ../../node_modules/@fastify/error/index.d.ts, imported by ../../node_modules/fastify/types/hooks.d.ts

I guess that error is due to #14. I'm not sure how to solve it, but the main issue here is that the underlying error was not reported.
