Hello dear Strapi !!

I have everything setup locally and everything is working fine. I use the latest version of Gatsby and Strapi. I have successfully deployed my strapi instance on Heroku (production server running successfully) but when my Gatsby Cloud starts the build, I always get the following error:

Failed to fetch data from Strapi connect ECONNREFUSED 127.0.0.1:1337

My question is: how does my apiURL should look like in the gatsby-config.js file ? Right now it looks like this: apiURL: http://localhost:1337. I tried to change it to my heroku url: https://gatsby-strapi-heroku.herokuapp.com but then, when I run gatsby develop I get graphql errors…

So the question is: how should I specify my apiURL on my gatsby-config.js file ?

Does anyone know how to fix this?
Thank you!

Is your host also herokuapp.com?

Yes, the app is hosted on Heroku.
I was able to solve this problem by checking my env variables on Heroku. The project was migrated from v3.6.5 to v4.5.5 and I forgot to set a new required variable.

In your particular case it look like you need to clear the Gatsby Cloud app cache because your front-end is trying to connect to localhost (127.0.0.1:1337). I would not recommend to set your API URL directly on gatsby.config.js for security reasons, instead you could use an enviroment variable to avoid publishing sensitive information.
