Logback-spring.xml unable to squash multiline stack trace to single line

I tried multiple solutions on SO, but none of them seem to be working for me. I am fairly new to Logback too, probably why I'm unable to find the right approach for my usecase.

Basically, we push logs to a centrally managed log service where we are required to send stack traces in a single line to avoid increasing the rate of ingestion (each line is a new log in the log service) and to make debugging easier.

Sample ERROR log:

14:50:41.856 ERROR [] 8 --- [trace=394a5287-6719-41b3-91e3-47b68b356856,span=394a5287-6719-41b3-91e3-47b68b356856] [jetty-274] c.e.f.s.c.a.controllers.BaseController : Error while processing request:

com.ExceptionClass : An exception occurred

at com.SomeClass.somefunction(SomeClass:237)

and so on, I want to have these all in a single statement

Here's how my logback-spring.xml file looks like

<?xml version="1.0" encoding="UTF-8"?>

I know that I need to update this line

    <property name="CONSOLE_LOG_PATTERN"
              value="%n%clr(%d{HH:mm:ss.SSS}){faint} %highlight(${LOG_LEVEL_PATTERN:-%5p}) [%marker] %clr(${PID:- }){magenta} %clr(---){faint} [trace=%X{X-Trace-Id:-},span=%X{X-Span-Id:-}] %magenta([%t]){faint} %yellow(%-40.40logger{39}){cyan}%clr(:){faint} %m${LOG_EXCEPTION_CONVERSION_WORD:-%throwable}%n" />

but I can't figure out how.

Here's what I tried

<property name="CONSOLE_LOG_PATTERN"
              value="%n%clr(%d{HH:mm:ss.SSS}){faint} %highlight(${LOG_LEVEL_PATTERN:-%5p}) [%marker] %clr(${PID:- }){magenta} %clr(---){faint} [trace=%X{X-Trace-Id:-},span=%X{X-Span-Id:-}] %magenta([%t]){faint} %yellow(%-40.40logger{39}){cyan}%clr(:){faint} %m${LOG_EXCEPTION_CONVERSION_WORD:-%throwable} %replace(%msg){'\n', ''}%n" />

but it did not work as expected

Thanks in advance
