I'm getting this error message in my logs

<B4IExceptionWrapper: Error Domain=caught_exception Code=0 "-[B4IList Keys]: unrecognized selector sent to instance 0x28398e190" UserInfo={NSLocalizedDescription=-[B4IList Keys]: unrecognized selector sent to instance 0x28398e190}>

no idea of what it means

1. This is an error caught with a Try / Catch block.
2. My guess: you are parsing json and expecting a map while receiving a list.

Found: I was converting the iterable list of a map keys into a list and sorting them

Switch to B4XOrderedMap. It allows you to do it.
