@loicmathieu I remove a lot of code in ForEach that didn't work in the past, TBH I didn't see why not reusing the already existing code?

[loicmathieu]

@tchiotludo this is not the same, resolveConcurrentNexts will resolve values concurrently but not subtasks, whereas resolveParallelNexts will resolve both values and subtasks concurrently which is what EachParallel is doing but we decided not to reproduce on ForEach with concurrency>1 as it creates too many concurrencies.

We had a long discussion about it.

So we need both methods as they do different things.

ok so my fix is not the good one, but each-error flow included failed to work with previous implementation, like all finally one
