Error Handling

It is recommended to always throw an Error class as an exception instead of returning just an error message. You may create your own Error Class within the src/exceptions/ directory.

import { MediaException } from 'src/exceptions';

const params = {
  someKey: 'someValue',
}

const validFields = [
  {
    key: 'someKey',
    type: 'string',
    required: true,
  }
]

try {
  return validateFields(params, validFields);
} catch (error: unknown) {
  throw new MediaException(
    'Invalid fields',
    `core.medias.getMedia::FIELD_VALIDATION_EXCEPTION`,
    400,
    { error, params }
  );
}

Custom Error classes

You can define your own Error classes as needed. Refer to the existing src/exceptions/ErrorException.ts class.
