SDK42 expo-fonts won't load TTF

Expo Development Tools
1

After upgrading my Bare Workflow project to Expo SDK 42 my icomoon font (TTF) won’t load anymore in a release build. It loaded fine in SDK 41. It loads fine in debug build. My other fonts (OTF) load fine in the release build. The error I’m getting is “Error: Could not create font from loaded data for ‘’”.

The changelog for SDK 42 isn’t mentioning anything.

Any idea what could be happening here?

Hey @rodneyrehm, is this occurring for ios, android, both? Can you share all the relevant versions for packages such as expo-font, expo-asset, expo, etc?

Cheers,
Adam

Hey @adamjnav,

upon further inspection this is only happening on iOS. Android is loading the TTF just fine.

expo@42.0.3
expo-asset@8.3.3
expo-font@9.2.1

not sure why it’s taken me so long to check this in Expo Go… But on iOS it fails with the following error:

[Unhandled promise rejection: Error: Unable to download file: Error Domain=NSURLErrorDomain Code=-1002 "unsupported URL" UserInfo={NSErrorFailingURLStringKey=my-fancy-icons.ttf, NSErrorFailingURLKey=my-fancy-icons.ttf, _NSURLErrorRelatedURLSessionTaskErrorKey=(]

On Android I see

[Unhandled promise rejection: Error: Resource ID #0x0]

I’m not sure where the unhandled promise rejection is coming from, though. I’m using

const [fontsLoaded, fontLoadingError] = useFonts({
  ...Ionicons.font,
  'my-fancy-icons': require('./assets/my-fancy-icons.ttf'),
  'my-fancy-font': require('./assets/my-fancy-font.otf'),
})

I have a similar problem with SDK42, my custom icons are not getting displayed on iOS using ‘react-native run-ios’ in the logs show this error

Error: Unable to download file: Error Domain=NSURLErrorDomain Code=-1002 "unsupported URL" UserInfo={NSErrorFailingURLStringKey=icomoon.ttf, NSErrorFailingURLKey=icomoon.ttf, _NSURLErrorRelatedURLSessionTaskErrorKey=(
