Help with custom-playback-channel-master error roInput

[tecnicosya]

I used the template called "custom-playback-channel-master", I just need put an m3u8 and I'm happy with it.
The sub menu working ok, here I have others m3u8.
I uploaded to Roku and work fine.
But when I check th DeepLinking on developers dashboard, say this:

Channels are required to support roInput events. Please ensure your manifest includes the supports_input_launch=1 entry and your channel properly handles roInput events.

I add this to the manifest:
supports_input_launch=1

And try again and have the same problem.
How can I will solve it?
