zlib.error: Error -3 while decompressing data: too many length or distance symbols
Question:
Encountering this error for decompressing chunks of a file.
I already decompressed successfully about 5 chunks of data.
But there is just one range of data that doens’t get decompressed.
The header should be right.
Header 78 9C
This is only a chunk of the whole file. The file itself consists of multiple compressed chunks.
