Pavel Kirpichenkov c5893913f3 [NI] Remove lambda coersion to Unit in case of error return type(s)
Coersion to Unit from error type leads to misleading type mismatches:
"expected <expected lambda return type> found Unit", despite no user-provided Unit / empty lambda.
These diagnostics were collected, but not reported before, and that had been disguising the issue for a while.
