Encountered the error message 'The function getStaticPaths is not defined' while working with Next.js

As a newcomer to Nextjs, I am currently working on a blog project utilizing the T3 Stack (Nextjs, Typescript, Prisma, tRPC). I have encountered an error while attempting to fetch post content by ID. Below are the relevant sections of my code. Any assistance would be greatly appreciated :)

This is the router snippet:

getPost: publicProcedure
    .input(
      z.object({
        postId: z.string(),
      })
    )
    .query(({ ctx, input }) => {
      const { postId } = input;
      return ctx.prisma.post.findUnique({
        where: { id: postId },
        include: { Category: true, author: true },
      });
    }),

And here's the postview component section:

export const PostView: FC<PostViewProps> = ({ id }) => {
  const { data } = api.posts.getPost.useQuery({ postId: id });

  return (
    <Container maxWidth="xl">
      <Box>
        <Image src={"/logo.png"} alt="logo" width={180} height={180} />
      </Box>

      <Typography variant="h4">{data?.title}</Typography>
      <Typography>{data?.content}</Typography>
    </Container>
  );
};

I have tried various solutions found online and consulted chatgpt, but unfortunately, I am still facing the same error.

Upon further investigation, it appears that there is a crucial step missing in the code snippet provided. To rectify this issue, ensure that your handler function is marked as async and uses await when querying Prisma.

getPost: customMethod
    .input(
      z.object({
        postId: z.string(),
      })
    )
    .query(async ({ ctx, input }) => {
      const { postId } = input;
      return await ctx.prisma.post.findUnique({
        where: { id: postId },
        include: { Category: true, author: true },
      });
    }),
