hi! When I have dynamic output and generate next ops with .map function I have a problem when something goes wrong and some of ops fails. When I run pipeline “from failure” it doesn’t run ALL the steps that would be run id pipeline didn’t fail. So really it runs only those steps that were already started. All others that were waiting for the starting are not seen at all. I think it is a bug.

I also noticed the same thing. I don't know if it's a bug but it'll be nice to hear from the Dagster team about this.

Hi Tomakhina. Which version is this occurring on? I've just tried this locally and I've been unable to repro: • if an error occurs between yielding dynamic outputs, reexecuting from failure will still reexecute that step and produce all the desired dynamic outputs • if an error occurs in the mapped op, each of the failed mapped ops will reexecute How does the situation you described above occur?
