Magento 2 cms 后端 javascript 错误 Uncaught SyntaxError: Invalid or unexpected token

Question

Suddenly I am having javascript error and cannot edit any cms page (cms/page/edit/page_id/45) or block. I have been trying to solve this for the past week with no success. I have also tried removing the modules that I have installed recently.

I did not touch any core files and I have updated file permissions but still get this error below in chrome console from the core static files

Answer 1

In my case, it was a database issue due to js injection. Patching a 3rd party extension fixed the issue.
