here is the complete error:

PrismaClientKnownRequestError: 
Invalid `prisma.user.create()` invocation in
/.../dev/resolvers/Mutation.js:25:36


  The provided value for the column is too long for the column's type. Column: <unknown>
    at PrismaClientFetcher.request (.../node_modules/@prisma/client/runtime/index.js:1:226003)
    at processTicksAndRejections (internal/process/task_queues.js:97:5) {
  code: 'P2000',
  meta: { column_name: '<unknown>' }
}

What DB and datatype are you using? It seems the value that you are adding is greater than what the datatype can hold.
