Typescript generated client does not include FileParameter when its in an Array

I saw #2973 and its fixing PR #2972 . But I still has this issue.

My nswag cli is NPM/Node and the nswag version is 13.10.8:

  "devDependencies": {
    "@types/node": "^14.14.32",
    "@types/react": "^17.0.3",
    "nswag": "^13.10.8",
    "typescript": "^4.2.3"
  }

But I still facing this issue. How should I get the fix?
