Answer 1

Without the source code, it is unlikely that you will be prompted.
But this error most likely indicates that the file name that was formed cannot be written (for example, it contains forbidden characters like "/", ":", etc.
it is very likely that they appeared when adding the date to the file name.

Answer 2
