initialize() of express-openapi 12.0.0 always throws exception on Windows

After the update to express-openapi 12.0.0 my CommonJS app crashes on Windows when I’m calling the initialize method from the express-openapi package:

Error [ERR_UNSUPPORTED_ESM_URL_SCHEME]: Only URLs with a scheme in: file, data are supported by the default ESM loader. On Windows, absolute paths must be valid file:// URLs. Received protocol 'c:'

For Windows, the issue can be solved by changing in openapi-framework/index.ts, line 238

from

const imported = await import(fsRoutesItem.path);

to

const imported = await import(`file:///${fsRoutesItem.path}`);

Of course, this is just a first dirty hack and not tested on other platforms than Windows. Can someone check this and provide a fixed version 12.0.1, please?

@robertkiel can you help here?

Haven’t tested the change on Windows yet … The CommonJS script / ES module loader of Node.js seems to require some special treatment for Windows.

Will try on Windows tomorrow.

Thanks! It works on Windows again.
