Netlify-integration build fails when I am trying to build my plugin locally

I am new to Netlify and was trying to create a new integration using the Netlify SDK create command wherein I selected ‘Build Event Handlers’ and ‘Integration UI’ as the boilerplate.

Once the integration is created, I am trying to build it locally (without changing anything) using ‘npm run build’. The netlify-integration build commands adds the path of the index.ts file to tsconfig.build.json under the include section but still the build fails with the error message “No inputs were found in the config file” possibly because the "" present in the path of index.ts file is getting treated as an escape character
What can I do to make sure that the build command points to the correct path of my index.ts file

Do you really need SDK, or are you good to go with a build plugin? I’m asking because at the moment, I haven’t seen any real production requirements from anyone for SDK, they just go down that path even though their requirements could be fulfilled by a simple build plugin.

As for the integration, I had this test repo setup a few weeks ago: hrishikesh-k/nf-3c (github.com). I just tried that and it appears to work.

I also updated the dependencies in case it was a version issue, but everything still appears to work.
