Error when compiling for CJS: "The current file is a CommonJS module..."

Description

When including openapi-fetch from a CommonJS module, we get the following error:

node_modules/openapi-fetch/dist/cjs/index.d.cts:10:8 - error TS1479: The current file is a CommonJS module whose imports will produce 'require' calls; however, the referenced file is an ECMAScript module and cannot be imported with 'require'. Consider writing a dynamic 'import("openapi-typescript-helpers")' call instead.

10 } from "openapi-typescript-helpers";
