Can't use auth middleware

[D3xime]

Hello,

I am new to Adonis framework, but i have some problems, i have followed the documentation and encounter a problem with the auth middleware.

router
.post('projects', async ({ auth }) => {
console.log(auth.user) // User
console.log(auth.authenticatedViaGuard) // 'api'
console.log(auth.user!.currentAccessToken) // AccessToken
})
.use(
middleware.auth({
guards: ['api']
})
)

Type script is advertising me about i can affect string to type never.
how can i achieve that ?

here is my auth middleware
import type { HttpContext } from '@adonisjs/core/http'
import type { NextFn } from '@adonisjs/core/types/http'
import type { Authenticators } from '@adonisjs/auth/types'

/**

• Auth middleware is used authenticate HTTP requests and deny
• access to unauthenticated users.
  /
  export default class AuthMiddleware {
  /*
  • The URL to redirect to, when authentication fails
    */
    redirectTo = '/login'

async handle(
ctx: HttpContext,
next: NextFn,
options: {
guards?: (keyof Authenticators)[]
} = {}
) {
await ctx.auth.authenticateUsing(options.guards, { loginRoute: this.redirectTo })
return next()
}
}

Thanks in advance for your help.
