Block is not supported by the selected generator

WARNING: Block world_entity_inrange_foreach is not supported by the selected generator. It will be skipped.

That's the message I see when I try to use for-each blocks and many other blocks that I have tried to add to my procedures. I would like if the reason is that I'm modding for the version 1.12.2 and you can´t use these new blocks or is something different that can be solved, and if it's possible, how?. Thanks.
