I couldn't find an issue. But here is my error:

Error: EISDIR: illegal operation on a directory, open '/Users/don.denton/GitProjects/my-project/server-sdk/'
    at Object.openSync (node:fs:601:3)
    at Object.writeFileSync (node:fs:2249:35)
    at generateSchema (file:///Users/don.denton/.npm/_npx/f0a53e56ae94fd64/node_modules/openapi-typescript/bin/cli.js:136:8)
    at async file:///Users/don.denton/.npm/_npx/f0a53e56ae94fd64/node_modules/openapi-typescript/bin/cli.js:209:7
    at async Promise.all (index 0)
    at async main (file:///Users/don.denton/.npm/_npx/f0a53e56ae94fd64/node_modules/openapi-typescript/bin/cli.js:199:3) {
  errno: -21,
  syscall: 'open',
  code: 'EISDIR',
  path: '/Users/don.denton/GitProjects/my-project/server-sdk/'
}

When I log out the outputFilePath.protocol right before this check, it is "file:" (with a colon). After this change, my error goes away and the task completes.

How to Review

How can a reviewer review your changes? What should be kept in mind for this review?

Not sure how to reproduce the error without my exact setup... just haven't looked into it. Hence, not adding a test at the moment.
