It appeared again in 3.21.3
I have
"expo" : {
"packagerOpts": {
"config": "metro.config.js"
}
}
metro.config.js
const blacklist = require('metro-config/src/defaults/blacklist');
module.exports = {
resolver: {
blacklistRE: blacklist([/.tmp\/.*/])
}
};
Packager started after explicitely adding “sourceExts” to app.json
"expo" : {
"packagerOpts": {
"config": "metro.config.js",
"sourceExts": ["js"]
}
}
