Args not typed on extendConnection resolver

[brandaspt]

I have the following code:

export const postQueries = queryField(t => {
	t.connectionField("getAllPublishedPosts", {
		type: PostType,
		cursorFromNode: ({ id }) => id,
		additionalArgs: {
			filter: nullable(stringArg()),
		},
		nodes: async (_, { first, after, filter }, { prisma }) => {
			const posts = await prisma.post.findMany({
				where: {
					AND: [
						{ published: true },
						{
							OR: filter
								? [
										{ content: { contains: filter, mode: "insensitive" } },
										{ title: { contains: filter, mode: "insensitive" } },
								  ]
								: undefined,
						},
					],
				},
				take: first + 1,
				skip: after ? 1 : 0,
				cursor: after ? { id: after } : undefined,
			})
			return posts
		},
		extendConnection: t => {
			t.int("totalCount", {
				resolve: (_, { filter }: { filter?: string }, { prisma }) => // args are not typed here. had to type manually
					prisma.post.count({
						where: {
							AND: [
								{ published: true },
								{
									OR: filter
										? [
												{ content: { contains: filter, mode: "insensitive" } },
												{ title: { contains: filter, mode: "insensitive" } },
										  ]
										: undefined,
								},
							],
						},
					}),
			})
		},
	})
})

I was expecting args to be typed on the extendConnection resolver but typescript keeps complaining that filter has any type. root and ctx are typed though...
Am I missing something?

I am seeing the same result.
