const properties = {};
  const parameters = bodyOverride || req.body;
  ourFields.forEach((fieldName) => {
    if (parameters[fieldName] !== undefined) {
      properties[fieldName] = parameters[fieldName];
      delete parameters[fieldName];
    }
  });
  const msProperties = {
    onBehalfOf: properties['ms.onBehalfOf'] || req.headers['ms-onbehalfof'],
    justification: properties['ms.justification'] || req.headers['ms-justification'],
    license: properties['ms.license'] || req.headers['ms-license'],
    approvalType: properties['ms.approval'] || req.headers['ms-approval'],

  // Validate licenses
  let msLicense = msProperties.license;
  if (!msLicense) {
    throw jsonError(new Error('Missing Microsoft license information'), 422);
  }
  msLicense = msLicense.toLowerCase();
  if (supportedLicenseExpressions.indexOf(msLicense) < 0) {
    throw jsonError(new Error('The provided license expression is not currently supported'), 422);
  }
  // Validate approval types
  const msApprovalType = msProperties.approvalType;
  if (!msApprovalType) {
    throw jsonError(new Error('Missing Microsoft approval type information'), 422);

function translateTeams(body) {
  let admin = body.selectedAdminTeams;
  let write = body.selectedWriteTeams;
  let read = body.selectedReadTeams;

  // Remove teams with higher privileges already
  _.pullAll(write, admin);
  _.pullAll(read, admin);
  _.pullAll(read, write);

  body['ms.teams'] = {
    admin: admin,
    push: write,
    pull: read,
  };

  delete body.selectedAdminTeams;
  delete body.selectedWriteTeams;
  delete body.selectedReadTeams;
}
