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 'Exceptions/MediaException';
...

try {
  return validateFields(params, validFields);
} catch (err) {
  throw new MediaException(
    err.message,
    `Core/medias/getMedia::FIELD_VALIDATION_EXCEPTION`,
    400,
    { params, err }
  );
}

Custom Error Classes

You can define your own Error Classes as required. Refer to the existing src/exceptions/ErrorException.js class.

Sentry

Lesgo! is pre-configured to work with sentry out of the box

Configuration

The sentry configuration for your application is located at src/config/sentry.js. Or copy this file to that path.

You may also simply update the respective environment files in config/environments/* as such:

# Whether to enable sentry or not
SENTRY_ENABLED="true"

# Where to send events
SENTRY_DSN="https://public@sentry.example.com/1"

# Minimal level for error reporting. Ref: https://github.com/winstonjs/winston#logging
SENTRY_LEVEL="error"

# Track release version and for sourcemaps reference
SENTRY_RELEASE="sls-my-project-maste"

Initialization

Call this as early as possible on any of your lambdas. A suggestion would be to put this inside of a middleware

import connectSentry from "Utils/sentry";

connectSentry();
