HLS Manifest file doesn't include EXT-X-KEY as documentation

Hi Support Team,

I follow the guidance and setup the speke-reference-server in my AWS account. Then, I configure the copyProtection API for the HLS endpoint of MediaPackage as [this doc](https://github.com/awslabs/speke-reference-server/blob/master/MEDIAPACKAGE_CONFIG.md#manual-configuration). When I start the live streaming, the video still plays but I don't see the EXT-X-KEY value in **index.m3u8** file. Below is the HLS Manifest . Note that I still use the System ID "**81376844-f976-481e-a84e-cc25d39b0b33**" . Please help advice on this.

Thanks,

Start by reviewing MEDIAPACKAGE_CONFIG.md and the copyProtection API configuration referenced in the report, then compare that setup with the supplied index.m3u8 manifest and System ID. Done means establishing whether the missing EXT-X-KEY is caused by the reference server or AWS MediaPackage and documenting the required next step.
