Avoid exception causes to stop Mono.zip immediately

Question

Is it possible to avoid that if one mono in mono.zip throws exception all other monos are stopping immediately? I want them to end normally and perhaps to handle the erroneous one by something like „.doOnError“ or „.continueOnError. Is that a way to go?

Yes, it's possible. You can use Mono.zipDelayError. As you can understand from the method's name, it delays errors from the Monos. If several Monos error, their exceptions are combined.

If you have to get the combined result anyway, zipDelayError is not the solution. Use the zip operator and handle the error case with a fallback operator like onErrorResume or retry on the zipped Mono or any upstream one.
