What is the current behavior?
When trying to build a js bundle and publish like we used to, webpack reported this error:
TypeError: Cannot read property ‘properties’ of undefined
If the current behavior is a bug, please provide the steps to reproduce.
it’s hard to give u the exact webpack.config.js because it our company’s project.
But after analyze the problem, i find out that the problem may happen when firstname.lastname@example.org trying to work with email@example.com, some json may be not compatible with the older version.
And after i downgrade my webpack to firstname.lastname@example.org, then there won’t be any error and the building can be done correctly.
What is the expected behavior?
