API Response Error: SCHEMA_VALIDATION_ERROR

Expo SDK
1

As of a few hours ago, my expo builds with exp build:android have been failing with the following error:

[exp] API Response Error: SCHEMA_VALIDATION_ERROR

This is a version of my code that successfully compiled a few days ago.

I’ve experienced glitches with expo’s cloud build process in the past, so I’m wondering if someone else is experiencing this now. If not, what is the schema this error might be referring to?

My complete log for exp build:android is:

Hi there!

In your pasted log, there are two issues that need to be addressed in your app.json:

• ‘icon’ should have dimensions 512x512, but the file at ‘./app/assets/images/gramm-icon-v3.png’ has dimensions 300x300.
• cannot access file at ‘./assets/images/gramm-icon-v3.png’ for field ‘loading.icon’.

The reason you weren’t seeing this error before was because we turned on stricter app.json validation this evening. In a future version of exp, this error will be made more clear.

Thanks!

@skevy Thanks a lot. Fixed.

@brightspot look for any warnings in your log when you run exp publish.

Hi Skevy,

Here is the warning I got

[exp] Warning: Problems validating fields in app.json. See https://docs.expo.io/versions/v17.0.0/guides/configuration.html.
[exp]  • 'ios.buildNumber' should match pattern "^[0-9]+$".
[exp]  • android should NOT have additional property 'permissions'.
[exp]  • should be integer.

Hi Skevy,

I recognize the problem is because of the warnings. How do give android permission in expo 17?

Hi there!

I am also getting the following error while publishing the appication

Failed to publish package: API Response Error: SCHEMA_VALIDATION_ERROR

I have the app running in Google Play Store and App Store. And today I had transferred my app in App Store from one apple account to another, I am not sure whether I am getting the error because of it.

This app used to successfully publish through expo earlier. I am not able to trace why this issue is occurring.

Any help at the earliest would be highly appreciated!

Thanks,
Chitra

@chitra05 can you post logs of this? The Warnings in those logs may be indicative of why you are getting this error

@brightspot i think the warning means that your app.json shouldnt have the property android.permissions

Hi @quinlanj,

Thanks for the response!

I had defined icon for ios and android in expo.json, which is not allowed!

“ios”: {
“buildNumber”: “2”,
“supportsTablet”: true,
“bundleIdentifier”: “xx.xxx.xxx”,
“icon”: “./image_path”
},
“android”: {
“versionCode”: 2,
“package”: “xx.xxx.xxx”,
“icon”: “./image_path”
}
