How to get value of custom field with enum (multi)?

I stacked on something which looks pretty trivial. Could you please help me to understand how to get value of enum (multi) field?

What I need to do is check if field “Dev Teams”( enum (multi) ) is set to “Doc”, and then assign the issue to a member of Doc team.

I am trying to do the following:

const entities = require('@jetbrains/youtrack-scripting-api/entities');

exports.rule = entities.Issue.onChange({
  title: 'assign issue if Dev Teams of task is Doc',
  guard: (ctx) => {
    if (issue.fields.Type.name == ctx.Type.Task.name) {
     console.log("Type = Task");
     const dt = issue.fields["Dev Teams"];
     console.log( "value="+dt.name);
      return true;
    }
  },
  action: (ctx) => {
               console.log("inside actions");
    const issue = ctx.issue;
// assign the issue
  },
                requirements: {
    Type: {
      type: entities.EnumField.fieldType,
      Task: {
        name: 'Task'
      },
      DevTeams: {
        name: 'Dev Teams',
        multi: true
      }
    },         
  }     
});

Unfortunately dt.name is almost undefined. 

I also found that I have to use forEach to get value of the field with multiple values, but 

dt.forEach(function (v) {
        console.log( "value="+dt.name);
});

also does not work. Could you please advise me how to get this value? Thank you.
