setUserRoles() gives Error: removed non-existent document when using publication Meteor.roleAssignment.find().observe()

[ggerber]

Hi,

I have this publication:

Meteor.publish('systems.list', function systemslist() {
  const self = this;
  if (populatedString(self.userId)) {
    const rolesHandle = Meteor.roleAssignment.find({'user._id': self.userId}).observe({
      added({scope}) {
        const system = Systems.findOne(scope, {fields: {name: 1}});
        if (populatedObject(system)) self.added('ManageSystems', scope, system);
      },
      changed({scope}) {
        const system = Systems.findOne(scope, {fields: {name: 1}});
        if (populatedObject(system)) self.changed('ManageSystems', scope, system);
      },
      removed({scope}) {
        self.removed('ManageSystems', scope);
      }
    });
    self.ready();
    self.onStop(() => {
      rolesHandle.stop();
    });
  } else self.ready();
});

I have this method:

const remove = args => {
  try {
    const {systemId, memberId} = args;
    Systems.remove(systemId);
    Roles.setUserRoles(memberId, [], systemId);
  } catch (err) {
    console.error('remove err', err);
  }
};

When the user executes the method the publication gives:

I made a repo: https://github.com/ggerber/roles_316

npm run x

signin as global@admin.com password: admin

right-click on the 'CHDM' button and choose 'delete'.

On the server the publication will give an error about removing a non-existing document

My bad, this was an issue in my own code and not an issue with Meteor roles.

Thanks
