"Feed Too Large" - Trying to Update my DP channel to SDK

I’m in the process of moving my Direct Publisher channel over to SDK. When testing my channel locally, the only thing that shows up after the load screen is “Feed is too large.” I guess it might have something to do with my JSON feed. My JSON feed continues to work without issue on my Direct Publisher channel. I have a total of 511 items listed within the JSON feed. What am I doing wrong?

Look at the template code, specifically

https://github.com/rokudev/rdp-to-scenegraph-channel-template/blob/a62db0b78453553f4146fdf41dc43b8bf8ba1845/components/content/RootHandler.brs#L8

The code sets a maximum size for the root feed download. This is a safe guard to ensure the channel starts up in a reasonable time, but you can try changing the code in your version of the template to a larger size.

Thank you. After altering the value from 500 to 1000, I get a spinning wheel as the channel eternally tries to load. Will keep working at it.
