Projects API broken due to header requirement

[PerfectedApp]

From GitHub page regarding Project API:

Note: The Projects API is currently available for developers to preview. During the preview period, the API may change without advance notice. Please see the blog post for full details. To access the API during the preview period, you must provide a custom media type in the Accept header:

application/vnd.github.inertia-preview+json

Source: https://developer.github.com/v3/projects/

Current error message from calling project API:

null 415 {
  message: “If you would like to help us test the Projects API during its preview period, you must specify a custom media type in the ‘Accept’ header. Please see the docs for full details.“,
