in case it helps anyone in the future, i just upgraded to react 16 and was using react-redux, react-router and react-router-redux and getting the same error. i had to use the @next version of react-router-redux to resolve it.
We really should have this thread on the
reactrepo.Well, since this is the rare bug with React itself, I’m closing this out. Thanks @gartz for the original heads up!
I’m guessing because CodeSandbox runs in an iframe and is shipped code/data externally, it doesn’t have the right security context to access the error object or stack trace.
