I don’t know if this is possible, but we have been getting reports with empty context about file/line and stack traces. The happened on other errors in the past as well, but here’s how the latest looks like:
There’s been other errors from this same release which contain all the typical information (stack trace, file/line, etc…).
If it’s technically possible, we would like to know as much as possible about where the SyntaxError occurred. In this particular case, it looks like an invalid RegExp, which I don’t see why it would cause any issues getting the stack trace.
