   @zxf216 This error happens when reading dictionary-encoded string values. 
Please check following:
   - Check whether the dictionary data is correct. Especially pay attention to 
the number of entries in the dictionary. The dictionary will anyway be read 
regardless of any filter, so I think it should be good according to your 
description. But please check it just in case.
   - Check what is the entry id when the exception happen. It probably is an 
undefined value.
   - Please also check the positions in the 
`StringDictionaryColumnReader::seekToRowGroup` call to see if any value is 
suspicious.
