About fallbacks

See original GitHub issue

Hello,

I’m using circuit breaker to hold calls to some third party APIs and I have a doubt about if it’s possible to get the exception in fallback function, cause I’m using the axios library and every response that’s not a status code 200 throws an exception and calls the fallback, so I would like to personalize the fallback function based on this status code. Is this possible?

@helio-frota thank you. It solved my problem. I had just to use error as the last parameter.


this.circuitRecommendByCity.fallback((cityName, err) => {
	return this.handleFallbackByCity(cityName, err);
});

I think it’d be great to have an example with this, cause I had to look at lib code to figure out that the last parameter is the error parameter.
