eas build:configure Error: Project config: Slug for project identified by “extra.eas.projectId” (my-app) does not match the “slug” field (). Learn more: https://expo.fyi/eas-project-id. How to change App Display Name in Expo Managed app after publishing to App Store? The slug needs to be unique and if you change it you’ll have to create a new app in the https://expo.dev
{
"expo": {
"name": "my-app",
"slug": "my-app",
"version": "1.0.0",
...
}
The first time you build with “eas build” you submit it to App Store Connect the expo will provide the name from the app.json field “name” as the display name in Play Store and App Store where the id needs to be unique. The display name does not. You can rebuild the app if you also change the version and change the name property in app.json
{
"expo": {
"name": "My new Display Name",
"slug": "my-app",
"version": "1.0.1",
...
}
Now only the display name will change
Solution
Bump the version one up together with change the name in app.json
