LogStash::Json::ParserError: Invalid numeric value: Leading zeroes not allowed

[valleram]

Hi,
I'm trying to parse some json strings which contain an integer field with the value duration":0000.
I tried to convert it to string type but didn't work. I'm still receiving the following error.

#<LogStash::Json::ParserError: Invalid numeric value: Leading zeroes not allowed

I used this configuration in the logstash.conf file

filter { json{ source => "message" } mutate { convert => { "duration" => "string" } } }

Can you help me?

Try running this filter before you parse the JSON. It might need tweaking to make the pattern more specific.
