How to format stacktrace in log4j2?

By default log4j2 prints stacktrace on multiple lines, separated by newline characters. Something like:

java.lang.NullPointerException: error enovountered
    at ...
    at ...
    at ...

I want my stacktrace on a single line, something like, essentially using | as a delimiter rather than \n

java.lang.NullPointerException: error enovountered at ... | at ... | at ...

How will I accomplish something like this in log4j2?

log4j2 log4j logging stack-trace

Use includeStacktrace for JsonLayout

        <JsonLayout complete="false" compact="false" includeStacktrace="false">
        </JsonLayout>
