Repro steps

I run “ng build --prod”.

The log given by the failure

ERROR in scripts.b8e8114c722336f4e67f.js from UglifyJs undefined

Desired functionality

Build succeeds without error.

Mention any other details that might be useful

  • it works without “–prod”
  • it works if I change “target” to “es2015” in src/tsconfig.app.json (now it’s “es5”) but I don’t want to loose IE11 support now.
  • I tried “–source-map” but it did not give more informations

thanks

everyone having this error, see the referenced issue in tether HubSpot/tether/issues/295

to get your apps working again lower the version from 1.4.5 to 1.4.4

removing tether dependency and removing it from scripts[] fixed my issue, I don’t need it as bootstrap 4 depends only on popper.js. But still the error is confusing
