If you added the return type annotation, tools and editors would complain with a (correct) error telling you that your function is returning a type (e.g. a dict) that is different from what you declared (e.g. a Pydantic model).

        assertTrue(bytesWritten > 0);

        // Verify data is written at correct offset
        assertEquals(3, dst[startOffset]);

        // Verify total parameter count at correct offset
        assertEquals(500, SMBUtil.readInt4(dst, startOffset + 3));

        // Verify total data count at correct offset
        assertEquals(1000, SMBUtil.readInt4(dst, startOffset + 7));
    }

## Recap { #recap }

You can add multiple body parameters to your *path operation function*, even though a request can only have a single body.

But **FastAPI** will handle it, give you the correct data in your function, and validate and document the correct schema in the *path operation*.

You can also declare singular values to be received as part of the body.

                "Should throw exception for ACE count > 4096");

        testBuffer[1] = 0x00; // padding

        // Then
