Need help setting up multiline parsers.

I have setup a multiline parser in my fluentbit.conf have tried the multiline parser with a base config on local cli and it seems to work there however when i add the parser to my production config the final optput is not taking the lines. below is my configuration that is not working. what am i missing
configs i tried locally :
`[SERVICE]
flush 1
log_level info
parsers_file parsers_multiline.conf

[INPUT]
name tail
path test.log
read_from_head true
multiline.parser multiline-regex-java

[OUTPUT]
name stdout
match *`
where parsers_multiline.conf contains the multiline parser
