Released v6
https://yulongkelly.herokuapp.com/ deployed to Heroku
I am using Mac and I connected a git hub repository to this app on Heroku. I want to make a change to my website deployed on Heroku before but failed, so I deleted the previous one and created a new app. I also deleted the master branch and create a new branch called main. However, when I deploy the web from the main branch on GitHub it builds successfully but there is an application error on this website. I used axios and fetched a asp.net web API but I have no idea what I should do.
I had the same issue and was able to solve it using this solution:
npm install serve --s
Replace scripts in package.json with this:
"scripts": {
"dev": "react-scripts start",
"start": "serve -s build",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject",
"heroku-postbuild": "npm run build"
}
For reference, this is where I found this solution (all the credit and thanks to this dev) https://dev.to/urosran/comment/n92j
