Impossible to set permission with ACL within buidler-hooks.js

[allemanfredi]

Hello,

I'm trying to assign a permission in postInit within buidler-hooks.js in this way:

postDao: async (
    { dao, _experimentalAppInstaller, log },
    { web3, artifacts }
  ) => {
    const ACL = artifacts.require('@aragon/os/build/contracts/acl/ACL')
    acl = await ACL.at(await dao.acl())
  },

...

postInit: async ({ proxy, log }, { web3, artifacts }) => {
    const CHANGE_VAULT_ROLE = await proxy.CHANGE_VAULT_ROLE()
    await acl.createPermission(
      appManager, //accounts[0]
      proxy.address,
      CHANGE_VAULT_ROLE,
      appManager
    )
  },

but when i call createPermission i receive ACL_EXISTENT_MANAGER and if i call revokePermission(appManager, CHANGE_VAULT_ROLE, appManager) i receive ACL_AUTH_NO_MANAGER.

I tried to call getPermissionManager before creating the permission, but i receive 0x0000000000000000000000000000000000000000.
