I wrote a bitcoin core parser, for my personal project and because it helped me to start understanding the bitcoin protocol as a data structure.
This project mainly parsers every blk file and creates the corresponding json with the deserialized information.
I launched the alpha version of the project and actually parserizes the information and converts it into a json file, my application worked fine until the blk file number 976, where I get an exception from the blockchain library and precisely in the ReadCompactSize operation, the exception is of the type
unknown file: Failure C++ exception with description "ReadCompactSize(): size too large: iostream error" thrown in the test body
I used the bitcoin core libraries for example serialize.h
I don't understand why this error only comes up to me after blk00976 blochi and for all the subsequent ones I tried also with the file blk00977 blk01124
I have some posts I have consulted and others where I asked about this problem, now I was opening an issue on github for bitcoins but there it is written that for general questions you have to refer here.
The questions I have read but do not solve the problem How to handle incomplete blocks when reading blk*.dat files?

Two words about the source code
I am a java programmer dealing with the bitcoin protocol and I decided to carry out the C ++ project to study the language too, so to those who linked the code I apologize if it looks like an offense because it is badly written but I am studying to refact and improve the performance of the parser but also the quality of the source code.
