Version Info
Apigee Edge Drupal integration ( hybrid)

[arlina-espinoza]

@arunz6161: Fixed this from the PHP client library. It requires PR's:

• [#296-apigee edge drupal] apigee-client-php#92
• Verify empty response on normalizeExpandFalseForHybrid(). apigee-client-php#91

I've updated our testing environment with all the required PR's/code.

[arlina-espinoza]

PRs merged, and issue should be fixed on the latest 2.x-hybrid client library.
