After a new deploy with no changes, both our Production and Staging backends API fetches from Forest Admin are timing out. Backend in deployed on Heroku and has been working good for a long time, the issue only started a few hours ago. The same code works on local development.

Hi @vigzmv !  
Do you have any logs on your frontend or backend ?  
There was no changes whatsoever on the deployment ? Can you compare the `.forestadmin-schema.json` between your environments ?  
I will checkout your project on my side !

Thanks for the help @anon94532230.

The issue is fixed, It was due to heroku using node 14.x  
There was no code or schema change at all, we just did a redeploy, on the new build heroku started using node 14.x as it seems that it is now the [active version for heroku](https://devcenter.heroku.com/articles/nodejs-support#supported-runtimes).

Setting node version in package.json fixed it.

```javascript
  "engines": {
    "node": "12.x"
  }

```
