I have configured raven-js to track errors from a React.js application. Sentry also finds the provided source maps from the JavaScript files and shows the errors with the real code.
My problem now is, that the same error does not get grouped because of slightly differences between the stack traces. Google Chrome shows variable with name ‘s’ while Firefox and Safari use a variable name ‘this’ and the error occurs on the same line, but different column.
What can I do so that these issues will get grouped together? It seems like that Sentry cannot group these issues because of different looking stack traces which seems to be the normal behaviour between browsers.
