Describe the Bug

Setting swcMinify: true in next config causes parameter arrays in OpenAPI documentation generated by next-swagger-doc / swagger-jsdoc to render only the last parameter in the array.

Expected Behavior

dev and prod output should not be different

To Reproduce

• yarn install to install dependencies
• When you run yarn dev, you should see all 3 params in the swagger documentation generated from the jsdoc in pages/api/hello.ts:

• However, when you create a production build with yarn build and run the production server with yarn start, all params but param3 are gone:

The root cause seems to be somewhere in swcMinify. Setting swcMinify: false in next.config.js and running yarn build and yarn start again results in the correct output.
