Changelog

Unreleased

  • Keep the crawler User-Agent when CloudFront does not forward it. The viewer-request function now stores the header value as a string (it stored the raw header object before, so the value was unusable), the origin-request function restores User-Agent from X-User-Agent, and the cache behavior forwards X-User-Agent. Without this, Prerender.io received Amazon CloudFront as the crawler identity.
  • Bumped the AWS::Lambda::Version logical IDs, so a stack update publishes new function versions.
  • Added the X-Prerender-Int-Version header (2.0.0), sent next to X-Prerender-Int-Type: cloudfront and forwarded by the cache behavior, so the origin of a request stays identifiable when the User-Agent is restored. Absence of the header means a stack older than 2.0.0.

Older notes

The runtime parameter of nodejs6.10 is no longer supported for creating or updating AWS Lambda functions. We recommend you use the new runtime (nodejs8.10) while creating or updating functions. (Service: AWSLambdaInternal; Status Code: 400; Error Code: InvalidParameterValueException; Request ID: 579f3922-7baa-11e9-adaf-11ff68a3ace1)
