Desired functionality.

The output should show the line number of the typescript file instead of the bundle.

Thanks for reporting this issue. However, this issue is a duplicate of an existing issue #6623. Please subscribe to that issue for future updates.

[danielsuter]

@filipesilva The other issue is closed and it's only stated that there's a problem when debugging through docker.
Imho this is not a duplicate or the other issue should be adjusted and reopened.

[filipesilva]

The issue I linked wasn't about docker, it's mentioned in the last comment by another user and nowhere else.

@clydin's comment (#6623 (comment)) indicates what the problem was and provides a fix in #6682. It should be in the latest release.

When using the latest release do you still experience this problem?

[filipesilva]

#6824 also reported the same in 1.1.3, will investigate.

[filipesilva]

I pushed a fix in #6862 that addresses part of the issue, restoring source maps test runs in the sources window:

I'm not sure that the other part of it, the error shown by the Karma console, is fixable though. I don't think that error uses sourcemaps, since it's a zone error. I tried using the @angular/cli@1.0.0 and it didn't seem to work there either. If you have a version of the CLI that correctly shows that error, please let me know.

[filipesilva]

The console error is being tracked in #6583.
