   Sorry for the slow response, I've been away for the last few days. My 
immediate hunch is that the writer is embedding a garbled arrow schema in the 
metadata.
   
   As part of the backwards compatibility logic documented in 
https://github.com/apache/parquet-format/blob/master/LogicalTypes.md#lists, the 
schema inference correctly interprets this as a list on read, which then errors 
because this doesn't match what has been written.
   
   This is a bug, which should be fixed, but I would also recommend writing a 
(LIST) type as documented in the link above - and not relying on a non-standard 
representation.
