> C2 Server can't get from NiFi templates with versions v10+, only v1-v9.
> The reason is an error in the "getConfiguration" function, where "filenamePattern" is
determined.
> Wrong code (maybe a typo?):
> {code:java}
> String filenamePattern = Arrays.stream(filename.split(Pattern.quote("${version}"), -1)).map(Pattern::quote).collect(Collectors.joining("([0-9+])"));
> {code}
> It should be:
> {code:java}
> String filenamePattern = Arrays.stream(filename.split(Pattern.quote("${version}"), -1)).map(Pattern::quote).collect(Collectors.joining("([0-9]+)"));
> {code}
> {code:java}
> [0-9+] -> [0-9]+{code}
