Build Error (UglifyWriter) 'return' outside of function #8251

Closed mapeveri closed 2 years ago

mapeveri commented 5 years ago

After run embe build --environment=production i have this issue:

Build Error (UglifyWriter)

'return' outside of function

Stack Trace and Error Report: /tmp/error.dump.b30ea78b6371081667862a3904960ded.log

With ember build, I do not have this problem.

Something in your codebase is invalid and throws an error when minified. Presumably the stack trace points you to more information about the error.

The reason it doesn't happen with ember build is that we don't run minfication there by default.

Hi @rwjblue, I understand. And how could I detect the error in my code?. Thanks!!

We have switched from Uglify to Terser. Hopefully nowadays you get a better error message!

return outside of a function isn't valid javascript, so it's likely one of your libraries is causing will need to be updated, patched, or PR'd to.
