Passing the LA_URL in the playready_extra_header_data is creating an invalid WRMHEADER.

<WRMHEADER xmlns="http://schemas.microsoft.com/DRM/2007/03/PlayReadyHeader" version="4.0.0.0"><DATA><PROTECTINFO><KEYLEN>16</KEYLEN><ALGID>AESCTR</ALGID></PROTECTINFO><KID>MDAwMDAwMDAwMDAwMDAwMA==</KID><CHECKSUM>+uPUuAgGBes=</CHECKSUM></DATA><LA_URL>https://proxy.uat.widevine.com/proxy</LA_URL></WRMHEADER>

LA_URL should be enclosed in the element. In fact, all the playready extra data should be enclosed in DATA element.
