I've been trying to fix this problem for 2-3 days but I'm unable to fix it. It occurs when I try building the Application with yarn build here's the error

> Build error occurred
TypeError: Cannot read properties of null (reading 'toString')

my code-

export async function getStaticPaths(){
  // get the user's image from another table 
 

  const users = await prisma.UserInfo.findMany();
  const paths = users.map((user: any) => ({
    params: { pid: user.name},
    // Error: A required parameter (pid) was not provided as a string in getStaticPaths for /users/[pid].
  
  }))
  console.log(paths)
  return { paths, fallback: false }

}
export async function getStaticProps({ params }: any) {
  const user = await prisma.UserInfo.findUnique({
    where: {
      name: params.pid
    },
  });
  console.log(user)
  return { props: { user } };
}

any ideas on how to fix this? thanks Great day'
