Font Error when debugging with cli

I suddenly started getting below error on code that is built and working in prod with no changes to the code.

I get the error when I try to run and debug locally using the expo cli and the exp app.

I stepped through the debugger and font loading code seems to be working.

fontFamily “Ionicons” is not a system font and has not been loaded through Font.loadAsync.

THis is where the font get loaded. Any suggestions would be appreciated. Thanks

export default class App extends React.Component {
state = {
fontLoaded: false,
isReady: false,

async componentDidMount() {

async loadFonts() {
await Font.loadAsync({
Roboto_medium: require(‘native-base/Fonts/Roboto_medium.ttf’),
await Font.loadAsync({
Roboto_light: require(‘./assets/fonts/Roboto-Light.ttf’),
await Font.loadAsync({
Ionicons: require(‘@expo/vector-icons/fonts/Ionicons.ttf’),
await Font.loadAsync({
Feather: require(‘@expo/vector-icons/fonts/Feather.ttf’),
await Font.loadAsync({
SimpleLineIcons: require(‘@expo/vector-icons/fonts/SimpleLineIcons.ttf’),
this.setState({ fontLoaded: true });

SDK 36

It turns out I was not on sdk 36, the expo upgrade had errored out on an npm issue.

I have now successfully upgraded to Sdk 36 and am getting the below font error.

Unable to resolve “@expo/vector-icons/fonts/Ionicons.ttf” from “App.js”
Failed building JavaScript bundle.

I tried these commands with no luck:

rm -rf $TMPDIR/react-* && rm -rf node_modules/ && rm -f package-lock.json && rm -f yarn.lock && npm cache verify && npm install && expo r -c

ANy suggestion would be greatly appreciate :slight_smile:

icon file paths changes, so got passed that error.

But now debugger does not work, and gives below error. I can build an APK, and verified the app is working, just getting this MEtro debugger error now.
