boolean | null auto translates to false ?

[JimmyBjorklund]

Hi
Have an update request that looks like this

interface UpdateRequest {
  u: boolean | null
}

@Put("g/{id}")
async updateU(id: string, @Body() body: UpdateRequest ): Promise<void> {
   console.log("update", body);
}

When trying to pass null to the variable u it auto translates to false instead of null that one would expect.
Is this expected?

Found another strang thing if i set
u: "null" | boolean;
Then passing both null and "null" seems to work, this seams wrong if i set a string "null" then null should not work ?
