const { ApplicationError, NotFoundError } = errors;

export default {
async beforeCreate(event) {
//todo add validation before create for mandatory field
},
async beforeDelete(event) {
const { params } = event;
const entry = await strapi.entityService.findOne(
“api::csdd-one-sim-parameter-td-authorization.csdd-one-sim-parameter-td-authorization”,
params.where.id,
{}
);

if (!entry) {
  //handle if already deleted
  throw new NotFoundError(
    `Entry ID: ${params.where.id} not found / already deleted!`
  );
} else if (entry.status === CollectionStatus.SUBMITTED) {
