See original GitHub issue🐞 Bug report
Command (mark with an x

Is this a regression?
Yes, didn’t see this with Angular 12.
Description
I’m running into Error: Content and Map of this Source is not available (only size() is supported) with Angular.
This seems to have been reported in various other places recently: stackoverflow.com/questions/70066980/angular-12-content-and-map-of-this-source-is-not-available-only-size-is-suppo
I’m not sure if this is an Angular or Webpack issue, I also crossposted this to webpack: https://github.com/webpack/webpack/issues/14840
🔬 Minimal Reproduction
I don’t have a clear reproduction, however I was able to add some logs in emitAsset
here, which is part of the stack trace:
https://github.com/webpack/webpack/blob/14582fc41504595b04f01561ea19d27391d6b9ac/lib/Compilation.js#L4171-L4176
I added:
emitAsset(file, source, assetInfo = {}) {
if (this.assets[file]) {
try {
!isSourceEqual(this.assets[file], source);
} catch (err) {
console.error(file, this.assets[file], source);
throw err;
}
The output before the crash is:
fontawesome-webfont.eot SizeOnlySource { _size: 165742 } RawSource {
_valueIsBuffer: true,
_value: <Buffer 6e 87 02 00 ac 86 02 00 01 00 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 00 90 01 00 00 00 00 4c 50 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ... 165692 more bytes>,
_valueAsBuffer: <Buffer 6e 87 02 00 ac 86 02 00 01 00 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 00 90 01 00 00 00 00 4c 50 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ... 165692 more bytes>,
_valueAsString: undefined
}
It always seems to crash on the same eot
file. Notice that this.assets[file]
for this file is a SizeOnlySource
.
