Are you using jest or chai?
n/a

Are you using OpenAPI 2, 3.0.X, or 3.1.0?
n/a

Describe the bug clearly
declarationMap and sourceMap are enabled in tsconfig.json

but the source code isn't included in the published packages, even though the .d.ts.map and .js.map files are

the source code should be included such that the declaration and source maps can be utilized by users for an improved development/debugging experience

Steps to reproduce the bug:

1. npm install openapi-validator
2. go to node_modules/openapi-validator
   

What did you expect to happen instead?
src directory is present with the source code
