PHP Warning: file_put_contents(/<path_to_bag>/bagit.txt): failed to open stream: No such file or directory in /<path_to_application>/vendor/whikloj/bagittools/src/Bag.php on line 1749
PHP Warning: copy(/<path_to_bag>/data/<some_file>): failed to open stream: No space left on device in /<path_to_application>/vendor/whikloj/bagittools/src/Bag.php on line 441
Return values of uses methods like mkdir(), copy(), file_put_contents(), ... should be evaluated and in case of an error maybe an exception with a good error message should thrown or something similar should be done.
