error: Uncaught InvalidData: data did not match any variant of untagged enum ArgsEnum

I have just two files list below, after Deno.env.get got 8083 from .env. But got an error. What can I do?

Edited: when I comment out all the dotenv related code, still got this error. Maybe it is not deno-dotenv problem, but I asked here to see if anyone knows what can I do.

Edited final: I know why is going wrong here... it must need to code: parseInt(Deno.env.get('PORT') so the new App(PORT) can be worked... I will close this issue later, Sorry to bother you!

server.ts

import { Application } from "https://deno.land/x/oak/mod.ts"
import 'https://deno.land/x/dotenv/load.ts'
const PORT = Deno.env.get('PORT')

console.log(PORT)

export class App {
  public app: Application
  public port: number
  public logger: any

  constructor(port: any) {
    this.app = new Application()
    this.port = port

    this.initializeMiddleware()
  }

  private initializeMiddleware() {
    this.app.use(async (ctx, next) => {
      await next()
      const rt = ctx.response.headers.get("X-Response-Time")
      console.log(`${ctx.request.method} ${ctx.request.url} - ${rt}`)
    })
  }

  public async listen() {
    console.log("Server is listening at http://localhost:", this.port)
    return await this.app.listen({ port: this.port })
  }
}

const app = new App(PORT)
app.listen()

.env

PORT=8083

No worries! That error isn't the most helpful. It looks like the newer version of server.ts handles this better, oak uses v0.54.
