Failed to compile message without any detail. #5008
Description
This is issue created for discussing fix of the weird common Alphas 2.0.0 error that looks like that:
I did some research trying to find the root cause and it seems that I found it.
Seems to be an issue in formatWebpackMessages.js
// Remove unnecessary stack added by `thread-loader`
var threadLoaderIndex = -1;
lines.forEach(function(line, index) {
if (threadLoaderIndex !== -1) {
return;
}
if (/thread.loader/i.test(line)) {
threadLoaderIndex = index;
}
});
if (threadLoaderIndex !== -1) {
lines = lines.slice(0, threadLoaderIndex);
}This piece is deletes everything after 'thread-loader'. So when you have an error or warning it will be striped out to the path only.
So message like that:
./src/elements/FormSignIn/index.js
Module Warning (from ./node_modules/thread-loader/dist/cjs.js): <<<< Takes this line index

@ ./src/App.js
@ ./src/index.js
@ multi ./node_modules/revolut-react-scripts/config/polyfills.js ./src/index.js <<< removes all till that line
End up like:
./src/elements/FormSignIn/index.js
So effectively changing
if (threadLoaderIndex !== -1) {
lines = lines.slice(0, threadLoaderIndex);
}to
if (threadLoaderIndex !== -1) {
lines.splice(threadLoaderIndex, 1);
}May fix this, I'm not sure about other errors and warnings formats so a little discussion will be a nice thing to do before I open a PR if you like.
