n8n and postgres deploy incompatibility version

Question

I am trying to use the fast deploy of n8n with heroku: link deploy

But, I get the following error:

We tried to create heroku-postgresql:essential-0, but received an error from the add-on provider. Try the request again, or log a support ticket and include this message: Unsupported version: 14. We support the following versions: 15, 16, 17

I checked the repository and found the problem in file app.json that contains:

"plan": "heroku-postgresql",
"options": {
   "version": "14"
}

I don't know how resolve this problem, what you should?

note: excuse my english, I am latin...
