Invalid @Args target

Reproduction

@Args() depends on the selected Command invocation and therefore cannot be injected into a constructor:

src/deploy.command.ts

Copy

import { Args, Command, Handler } from 'func'
import type { Args as CommandArgs } from 'func'

@Command('deploy')
class DeployCommand {
  constructor(@Args() args: CommandArgs) {}

  @Handler()
  run() {}
}

How to fix it

Move the parameter to an @Handler() method:

src/deploy.command.ts

Copy

class DeployCommand {
  @Handler()
  run(@Args() args: CommandArgs) {
    console.log(args.inputs)
  }
}

When a constructor needs invocation context, inject Context instead. details.target and details.index identify the invalid class and parameter position.
