Issue with a Music Skill, as follows.
The Music Skill invocation name is 'great radio'. The skill passes all validation tests.
The 'Catalog' of stations has been uploaded and associated with the skill, and the ER_INGESTION is SUCCEEDED. One of the 240 entities is named 'Smooth Jazz'.
This voice command - 'Alexa, play smooth jazz on great radio' - results in 'I could not find that on great radio'. The skill's lambda function is not invoked by this voice command. Any command to play a specific station/entity fails in the same way.
This voice command - 'Alexa, play music on great radio' - invokes the the skill's lambda function as expected, and a stream can be played.
What have I overlooked? I have deleted everything and started over, but get the same results. I have read the troubleshooting guide and documentation three times, to insure I've not missed something. I am ready for help and guidance!
