    ref: "employee",
  },
  project: String,
  organization: String,
});

  let employee_info = await Storage.employeeInfo
    .find()
    .where({ employee_id: emp_id })
    .populate({
      path: "client",
    })
    .exec(function (err, block) {

      }
      console.log("Employee details is %s", employee_info);
    });

  return employee_info;

CodePudding user response：

Try to change your GetEmployeeDetails method like this:

async function GetEmployeeDetails(emp_id) {
  try {
    let employee_info = await Storage.employeeInfo
      .find({ employee_id: emp_id })
      .populate('client')
      .exec(function (err, block) {
        if (err) console.log('%s', err);
        else console.log('Employee details is %s', employee_info);
      });

    return employee_info;
  } catch (err) {
    res.status(400).send('Error getting details');
  }
}
