Is the pipeline config below possible?

input {  
beats {  
port =\> "5601"  
}  
}  
filter {  
mutate {  
remove\_field =\> ["@version","@timestamp","path","host", "beat", "message"]  
}  
}  
output {  
stdout {  
codec =\> avro { schema\_uri =\> "/tmp/avrotest.avsc" }  
}  
}

Getting Error:

{"masked", "masked"=\>"masked", "masked"=\>"masked"} is not an example of schema

Does a trivial example work at all? Looks like you have a schema error

I Found the schema error but unable to find the right avro data type.

Error:

The datum {"Masked"=\>#BigDecimal:662a4aa0,'0.455E2',3(4)} is not an example of schema {"type":"record","name":"outer\_record","fields":[{"name":"Masked","type":"double"}]}\>

Tried using avro type float, java math decimal and decimal with precision, none worked

can I mutate convert that field so that it will out as double or float not BigDecimal:662a4aa0,'0.455E2',3(4)?
