Hi there,

I'm having trouble with my config file that I want to use.  
I'm using windows 10 and the 6.5.1 version of elastic, kibana and logstash.  
I've encountered quite a few errors but until now I've been able to solve them with topics on here, but now I'm stuck.  
The error I get tells me this:  
Error: Unknown error (SystemCallError) 123 - FindFirstFile

This is the config file I'm using:

input {  
file {  
path =\> "/C:/Users/acer/Documents/Data/cursisten.csv"  
start\_position =\> "beginning"  
sincedb\_path =\> "nul"  
}  
}  
filter {  
csv {  
separator =\> ","  
columns =\> ["nummer", "ID", "achternaam", "voornamen", "roepnaam", "datum van inschrijving", "BOW registratienummer", "einddoel", "soort cursus", "start", "einde", "bet", "max", "kosten", "cursus"]  
}  
mutate {convert =\> ["nummer", "integer"]}  
mutate {convert =\> ["ID", "integer"]}  
mutate {convert =\> ["BOW registratienummer", "integer"]}  
mutate {convert =\> ["kosten", "float"]}  
}

output {  
stdout { codec =\> rubydebug }  
elasticsearch {  
hosts =\> ["localhost:9200"]  
index =\> "cursisten"  
}  
}

This error will come up and it will start over until the error pops up again

[2018-12-05T10:39:28,813][ERROR][logstash.pipeline] A plugin had an unrecoverable error. Will restart this plugin.

Error: Unknown error (SystemCallError) 123 - FindFirstFile  
Exception: SystemCallError

I don't know where I go wrong, but it probably something in my config file.  
If someone can help me find it out it would help me so much.  
Thanks in advance!
