Error: Unable to find entry for [...]

[alexgorbatchev]

I'm trying to use the gulp plugin and it doesn't seem to work.

gulp.task('test:remap-istanbul', function() {
  var remapIstanbul = require('remap-istanbul/lib/gulpRemapIstanbul');
  return gulp.src('coverage/coverage.json')
    .pipe(remapIstanbul({
      reports: {
        'html': 'coverage/html-report',
      }
    }));
});

Throws this error:

gulp test:remap-istanbul

However, from command line with everything else being the same, it works wonderfully:

$ ./node_modules/.bin/remap-istanbul -i coverage/coverage.json -o coverage/html-report -t html

What am I doing wrong?

[kitsonk]

I think this had a fair amount to do with the issues encountered when using sources contained in a source map. Could you try 0.6.3 and see if the issue persists?

[EarthCitizen]

I am seeing the same issue in 0.6.4 via karma-remap-istanbul 0.2.1

I am having the same error when running the same thing.

@bertofer If you are executing remap-istanbul through karma-remap-istanbul, you can disable the HTML reporting for karma-remap-istanbul and just execute remap-istanbul after Karma runs. This is what several people have done while this issue remains unresolved. I did this myself. I only have the issue when karma-remap-istanbul executes/uses remap-istanbul.

This may turn out to be an issue with karma-remap-istanbul, or with the API that karma-remap-istanbul uses.

[Elecash]

I can confirm that this is not happening in v0.5.1 to me.

I hope that this leads you to the problem :)

[majanord]

I'm getting this error:
UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): Error: Unable to find entry for ....
or something similar when using version 0.7.0 -> 0.9.5 while it there's no error from 0.5.1 - 0.6.4 thx for the idea for the temporary fix @Elecash .

[pgarge]

Version 0.9.5 was working with Angular 4 and html report was generated.

If I upgrade to Angular 5 and keep all the other packages same I get the same error.

If I comment the html reporting line there is no error.

Versions lower than 0.7.0 don't work with Angular 5 either.
