Troubleshooting

Solutions to common issues when building native apps with Capgo Cloud Build.

Build Failures

”Upload failed” or “Connection timeout”

Symptoms:

• Build fails during project upload
• Timeout errors after 60 seconds

Solutions:

1. Check your internet connection

   # Test connection to Capgo
   curl -I https://api.capgo.app

2. Reduce project size

   • Ensure node_modules/ is not being uploaded (should be auto-excluded)
   • Check for large files in your project:

   find . -type f -size +10M

3. Check upload URL expiration

   • Upload URLs expire after 1 hour
   • If you get an expired URL error, re-run the build command

Astuce

Large projects (>200MB) may hit timeout limits. Contact support for enterprise options.

”Build timeout after 10 minutes”

Symptoms:

• Build exceeds maximum allowed time
• Status shows timeout

Solutions:

1. Optimize dependencies

   • Remove unused npm packages
   • Use npm prune --production before building

2. Check for network issues in build

   • Some dependencies may download large files during build
   • Consider pre-caching with a lock file

3. Review native dependencies

   # iOS - check Podfile for heavy dependencies
   cat ios/App/Podfile
   
   # Android - check build.gradle
   cat android/app/build.gradle

4. Contact support

   • If your app legitimately needs more time
   • We can adjust limits for specific use cases

Authentication Issues

”API key invalid” or “Unauthorized”

Symptoms:

• Build fails immediately with authentication error
• 401 or 403 errors

Solutions:

1. Verify API key is correct

   # Test with a simple command
   npx @capgo/cli@latest app list

2. Check API key permissions

   • Key must have write or all permissions
   • Check in Capgo dashboard under API Keys

3. Ensure API key is being read

   # Check environment variable
   echo $CAPGO_TOKEN
   
   # Or verify local .capgo file
   cat .capgo

4. Re-authenticate

   npx @capgo/cli@latest login

”App not found” or “No permission for this app”

Symptoms:

• Authentication works but app-specific error

Solutions:

1. Verify app is registered

   npx @capgo/cli@latest app list

2. Check app ID matches

   • Verify capacitor.config.json appId
   • Ensure command uses correct app ID

3. Verify organization access

   • Check you’re in the correct organization
   • API key must have access to the app’s organization

iOS Build Issues

”Code signing failed”

Symptoms:

• Build fails during code signing phase
• Xcode errors about certificates or profiles

Solutions:

1. Verify certificate type matches build type

   • Development builds need Development certificates
   • App Store builds need Distribution certificates

2. Check certificate and profile match

   # Decode and inspect your certificate
   echo $BUILD_CERTIFICATE_BASE64 | base64 -d > cert.p12
   openssl pkcs12 -in cert.p12 -nokeys -passin pass:$P12_PASSWORD | openssl x509 -noout -subject

3. Ensure provisioning profile is valid

   • Check expiration date
   • Verify it includes your App ID
   • Confirm it includes the certificate

4. Regenerate credentials

   • Delete old certificate/profile
   • Create new ones in Apple Developer portal
   • Re-encode and update environment variables

”Provisioning profile doesn’t include signing certificate”

Symptoms:

• Xcode can’t find certificate in profile

Solutions:

1. Download latest profile from Apple

   • Go to Apple Developer → Certificates, IDs & Profiles
   • Download provisioning profile
   • Ensure it includes your certificate

2. Verify certificate is in profile

   # Extract profile
   echo $BUILD_PROVISION_PROFILE_BASE64 | base64 -d > profile.mobileprovision
   
   # View profile contents
   security cms -D -i profile.mobileprovision

3. Recreate profile with correct certificate

   • In Apple Developer portal, edit profile
   • Ensure your distribution certificate is selected
   • Download and re-encode

”App Store Connect authentication failed”

Symptoms:

• Upload to TestFlight fails
• API key errors

Solutions:

1. Verify API key credentials

   • Check APPLE_KEY_ID (should be 10 characters)
   • Check APPLE_ISSUER_ID (should be UUID format)
   • Verify APPLE_KEY_CONTENT is correctly base64-encoded

2. Test API key locally

   # Decode key
   echo $APPLE_KEY_CONTENT | base64 -d > AuthKey.p8
   
   # Test with fastlane (if installed)
   fastlane pilot list

3. Check API key permissions

   • Key needs “Developer” role or higher
   • Verify in App Store Connect → Users and Access → Keys

4. Ensure key is not revoked

   • Check in App Store Connect
   • Generate new key if needed

”Pod install failed”

Symptoms:

• Build fails during CocoaPods installation
• Podfile errors

Solutions:

1. Verify Podfile.lock is committed

   git status ios/App/Podfile.lock

2. Test pod install locally

   cd ios/App
   pod install

3. Check for incompatible pods

   • Review Podfile for version conflicts
   • Ensure all pods support your iOS deployment target

4. Clear pod cache

   cd ios/App
   rm -rf Pods
   rm Podfile.lock
   pod install
   # Then commit new Podfile.lock

Android Build Issues

”Keystore password incorrect”

Symptoms:

• Build fails during signing
• Gradle errors about keystore

Solutions:

1. Verify keystore password

   # Test keystore locally
   keytool -list -keystore my-release-key.keystore
   # Enter password when prompted

2. Check environment variables

   # Ensure no extra spaces or special characters
   echo "$KEYSTORE_STORE_PASSWORD" | cat -A
   echo "$KEYSTORE_KEY_PASSWORD" | cat -A

3. Verify base64 encoding

   # Decode and test
   echo $ANDROID_KEYSTORE_FILE | base64 -d > test.keystore
   keytool -list -keystore test.keystore

”Key alias not found”

Symptoms:

• Signing fails with alias error

Solutions:

1. List keystore aliases

   keytool -list -keystore my-release-key.keystore

2. Verify alias matches exactly

   • Alias is case-sensitive
   • Check for typos in KEYSTORE_KEY_ALIAS

3. Use correct alias from keystore

   # Update environment variable to match
   export KEYSTORE_KEY_ALIAS="the-exact-alias-name"

”Gradle build failed”

Symptoms:

• Generic Gradle errors
• Compilation or dependency issues

Solutions:

1. Test build locally first

   cd android
   ./gradlew clean
   ./gradlew assembleRelease

2. Check for missing dependencies

   • Review build.gradle files
   • Ensure all plugins are listed in dependencies

3. Verify Gradle version compatibility

   # Check gradle version
   cat android/gradle/wrapper/gradle-wrapper.properties

4. Clear Gradle cache

   cd android
   ./gradlew clean
   rm -rf .gradle build

”Play Store upload failed”

Symptoms:

• Build succeeds but upload fails
• Service account errors

Solutions:

1. Verify service account JSON

   # Decode and check format
   echo $PLAY_CONFIG_JSON | base64 -d | jq .

2. Check service account permissions

   • Go to Play Console → Setup → API Access
   • Ensure service account has access to your app
   • Grant “Release to testing tracks” permission

3. Verify app is set up in Play Console

   • App must be created in Play Console first
   • At least one APK must be uploaded manually initially

4. Check API is enabled

   • Google Play Developer API must be enabled
   • Check in Google Cloud Console
