hpcnx opened a new issue, #2323:
URL: https://github.com/apache/logging-log4j2/issues/2323
## Description
When doing logj42 logging: '{"key":{}}'
saw exception like this:
Caused by: java.lang.IllegalArgumentException: found 1 argument
placeholders, but provided 0 for pattern
It does not happen with log4j
Have you seen related issue reported or fixed yet.
Could you please share any information if the issue had been fixed another
newer log4j2?
Thanks
