Navigator not showing contracts

New to Daml
1

I have a template and a script that creates and updates a contract. When running the script, the contract creation and modification displays correctly. But Navigator does not show the contracts. It only shows the template.

I followed the two suggestions elsewhere in this forum for a similar issue: using PartyIdHint and removing ‘parties’ from daml.yaml. But that doesn’t help. Any suggestions will be very helpful!

Here is my code:

daml.yaml

sdk-version: 2.3.2
name: college
source: daml
init-script: Main:setup
version: 0.0.1
dependencies:
  - daml-prim
  - daml-stdlib
  - daml-script
parties:
  - Prof
  - Student

Course.daml

module Course where

template Gradebook 
    with
        professor: Party
        student: Party
        courseId: Text
        score: Int
    where
        signatory professor
        observer student
        
        choice UpdateGrade: ContractId Gradebook
            with
                newCourseId: Text
                newScore: Int
            controller professor
                do
                    newGradeBook <- create Gradebook
                        with
                            professor
                            student
                            courseId = newCourseId
                            score = newScore
                    return (newGradeBook)

Main.daml

module Main where

import Daml.Script
import Course
import DA.Assert (assertEq)

setup : Script()

setup = script do

  prof <- allocatePartyWithHint "Prof" (PartyIdHint "Prof")
  student <- allocatePartyWithHint "Student" (PartyIdHint "Student")

  gradebookId <- submit prof do
    createCmd Gradebook { professor = prof, student = student, courseId = "101", score = 0}

  gradebookId <- submit prof do
    exerciseCmd gradebookId UpdateGrade { newCourseId = "101", newScore = 10}

  Some id <- queryContractId prof gradebookId
  assertEq id.score 10

Could you please try to start the navigator with the user management disabled?

I modified daml.yaml with

navigator-options:
  - --feature-user-management=false

followed by

daml start

but that doesn’t help.

Could you also remove the parties section as well? When you start the navigator you should see long party IDs like ::, otherwise your navigator did not query the allocated parties properly.

Thanks @Mate_Varga, yes that worked. Now I can see the contracts.
