In 1.12.2 /summon used to fail for falling_block if the specified block was not valid:
In current versions this is not the case and there is not even an error message in the log.
For endermen the command did not fail unless you provided an invalid short (for example 32768s) but it used the outdated integer id system anyways.
- Try summoning an enderman holding an invalid block
- Try inspecting its carriedBlockState tag
→ It does not exist
- Try summoning a falling_block entity for an invalid block
- Inspect its BlockState tag
→ It defaulted to sand
