you have to import the exported file, not the module

I did the same operation as in the video. I imported the exported .po file to my module. However, the error did not resolve. When I debug the error detail, I saw that this error was frozen from the file named "convert.py". (I am sharing the file below) I added the .po file extension here. However, I still could not translate my module.

with file_open(pathname, 'rb') as fp:
if ext == '.csv':
convert_csv_import(cr, module, pathname, fp.read(), idref, mode, noupdate)
elif ext == '.sql':
convert_sql_import(cr, fp)
elif ext == '.xml':
convert_xml_import(cr, module, fp, idref, mode, noupdate)
elif ext == '.js':
pass # .js files are valid but ignored here.
elif ext == '.po':
pass # .po files are valid but ignored here.
