[Question]: Recent need for API key undocumented in this repo

[dls314]

Question

The docs in this repo https://github.com/swagger-api/swagger-codegen/blob/master/docs/online-generators.md don't mention that this functionality seems to be blocked behind the need for an API key on swagger.io starting recently (I'm unsure if auth is required or if the API was impaired)

Is this expected?
Are there new docs?

Hi @dls314!. Thanks for the question. The root cause of the 500 error was that each fileId is valid only once, so subsequent requests tried to access a file that had already been deleted. Because the code attempted to read the file before checking whether it still existed, it triggered an exception instead of returning the intended 404. The prepared fix #12651 adds a proper null/filename check, removes file from map and returns 404 when the file has already been consumed, ensuring the response now matches the documented behavior. The fix will be included in the next release.
