the best ranks plugin error

[foggy oyster]

https://pastebin.com/VmCSnELV can someone help me understand this error please

[harsh nova]

i dont know the plugin, but there is:
java.lang.NumberFormatException: empty String

so an empty string is being provided and the plugin tries to parse it into a Double which causes a NumberFormatException.

My guess would be, that /ranks is missing further input/arguments

I've been looking at the source code to try and figure out what's going on and it seems like the problem stems from one of your requirements. It seems like maybe one of your placeholders are not actually being parsed to a value? I'm not exactly sure.

The string provided to StringUtils is empty

Also I'm pretty sure java has a Double.parse() method.
If you're doing this from a command arguments start at the index of zero.

That is not their code.

It's a plugin they use. I just found the source code

online

Oh okay I thought they were making it

[coral jackal]

The parse method that they have there is a bit more complicated I believe and actually what it does is that it ignores all other characters that were non digits

Interesting maybe that's why it says empty string
