According to your log, you are using 1.16.4, but this problem may be in many versions, I also encountered it, and it has been bothering me for a long time.
Check the error log found because the file does not have read permission, the problem may come from the https://github.com/swaggo/swag/blob/v1.16.4/parser.go#L1777, I doubt there is no check os.FileInfo and error.

If allowed, I would like to submit a 'pull request' to have it display the correct error content
