There was a problem hiding this comment.
This was also throwing the following error:
TypeError: Failed to execute 'text' on 'Response': Illegal invocation
because text() was being called outside of the response context.

I think this is good for now. But we just do a try catch block around all our sagas and log them.

Due to the way sagas work, the errors thrown in our nested sagas are seen as uncaught and redux saga hides most of the internal properties of the thrown error and just shows the
message, which isn't very helpful.redux-sagaprovides anonErrorhook that you can use for catching these errors at the root level, but theonErrorwill only get called if the caught error is of typeError. Since we defined our own error typeResponseErrortheonErrorhook never gets called. We need to update toredux-saga@1.0.0for that check to be fixed, but this might incur some other breaking changes that I don't think this PR should deal with. See this issue for reference.For now, we will surface the error in its entirety through
console.error().Before the change:
