}

Psalm output (using commit 6ad5e1c):

ERROR: MismatchingDocblockReturnType - 32:16 - Docblock has incorrect return type 'Generator<mixed, array<array-key, mixed>, mixed, mixed>', should be 'void'

ERROR: InvalidReturnType - 32:16 - No return statements were found for method Test::uploadFromCallable but return type 'Generator<mixed, array<array-key, mixed>, mixed, mixed>' was expected
