Reading json from iso file

[elungu3]

Hello @clalancette , @zekaizer , @ticky ,
I've been trying to read/load data from a json within an iso file. Using listchildren method I can see that the file is there, but I cannot do any operation on it. I've been trying to use some of your examples:

with iso.open_file_from_iso(iso_path='/myfile.json') as infp:
json_data = json.loads(infp)
# Assuming the JSON data is in UTF-8 encoding
json_content = json_data.decode('utf-8')
print(json_content)
iso.close()

but I get: pycdlib.pycdlibexception.PyCdlibInvalidInput: Could not find path
even tho if I extract files from the iso I have myfile.json in the root.

As extra info, I have an iso file that has 3 files within, one of them being a json file from which I need to extract data without extract all the files if possible.

Please advise :(
