Hello together,

I am new in the Elasticsearch Ecosystem. For that reason, I have unfortunately some problems with the syntax of Ruby in Logstash.  
I have the following snippet code:  
`if [Clat] != '' { ruby { code => " if !event['Clat'].to_s.include? "." event['Clat'].to_f event['Clat'] = event['Clat'] * 360 / (4294967296) event['Clat'] = event['Clat'].round(2) else event['Clat'].to_f event['Clat'] = event['Clat'].round(2) end " } }`  
Other parts of the code are working. The error message is:  
`Error: Expected one of #, {, } at line 42, column 50 (byte 1145) after filter{`  
It points on my first line:  
`if !event['Clat'].to_s.include? "."`

Probably, logstash has problems with the ruby syntax.

Do you maybe know where the problem can lie? I googled for the ruby syntax and created with that the corresponding ruby code.

Best regards

The code block itself is double quoted so you can't have double quotes inside it unless you escape the quotes. I suggest you go with single quotes in all places of your code.
