Is there a way to ignore it?

eval is the standard mechanism for ignoring errors. If eval isn't working for you, and you want help, you need to post some code

I can't post my code due to my internship, so here is the general :

$zip = Archive::Zip->new();

eval {$zip->read($filename);};
if($@) { print "Couldn't unzip $filename\n";}

Archive::Zip's read method is documented to return an integer to signal an error, it won't die

Your actual code isn't required, just something that triggers the same error/problem, and something that doesn't require purchasing a special brand of soap, something self contained
