Hey @zzaaxx,
We’ve published some sample code as a gist which will let you debug this easier on the frontend: https://gist.github.com/lgladdy/e4cb5816c835b11dd2d8f482b16fdcb6
It will output a backtrace where the error is happening, so only useful for local development instances.
Could you let us know what the raw value is for the second row in that repeater? It is likely to be some other character which has become a safe htmlentity.
