Can't restart Fluent Bit service

Question

I am using the "td-agent-bit" service to collect the logs of my app1 node application into a file named "file.log". In my "td-agent-bit.conf" file I left the [SERVICE] section unchanged, but I changed the [INPUT] and [OUTPUT] sections:

...
[INPUT]
    Name forward
    Listen localhost
    Port 24224

[OUTPUT]
    Name        file
    Match       *
    Path        /etc/td-agent-bit/file.log
    Format      json

The "file.log" exists and has all the permissions because I launched the command

sudo chmod 777 file.log

But when I do

sudo service td-agent-bit restart

I get the following error:

× td-agent-bit.service - TD Agent Bit

Answer 1

I just removed

Format      json

from the "td-agent-bit.conf" file and it has restarted properly.
