Same here, coverage report itself/remap works though.

Also seeing this.

So is remap-istanbul being fed incorrect values? It's not returning any "matches" in the remap function in remap.js.

Starting at line 255, this is where the errors are being thrown:

if (!match || !rawSourceMap) {
	/* We couldn't find a source map, so will copy coverage after warning. */
	warn(new Error('Could not find source map for: "' + filePath + '"'));
	try {
		fileCoverage.code = String(fs.readFileSync(filePath)).split('\n');
	}
	catch (error) {
		warn(new Error('Could find source for : "' + filePath + '"'));
	}
        srcCoverage[filePath] = fileCoverage;
	return;
}

I'm seeing that match is "null" and rawSourceMap is "undefined".

@gdi2290 - I'll see to this after work

[joshwiens]

As a temporary work around, lock istanbul-instrumenter-loader to 0.2.0 until I can get a fix for this landed in master.

[PatrickJS]

@d3viant0ne thanks for looking into it

Thanks for the heads up, but fixing the version to 0.2.0 does not work for me.

[joshwiens]

@centigrade-thomas-becker - I've evidently deviated too far from the starter where that change was effective. Working this issue again against current master.

[nqcuong72]

I have the same problem with version 0.2.0. It does not work
