Issue: Exception in stack trace is split across multiple lines causing too many logs.

Bug 6422: https://dev.azure.com/OpenEnergyPlatform/Open%20Energy%20Platform/_workitems/edit/6422

Impact: This issue is resulting in too many logs. Also impacts DRI's troubleshooting.

Target: Remove extra line or new line in exceptions so as to have more manageable logs.

log4j2.xml updated to remove new line character and add pipe separator instead. Code update: Original line 35 of log4j2.xml: <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss.SSS} %5p ${hostName} --- [%15.15t] %-40.40c{1.} correlation-id=%X{correlation-id} data-partition-id=%X{data-partition-id} api-method=%X{api-method} operation-name=%X{operation-name} user-id=%X{user-id} app-id=%X{app-id}:%m%replace{%m}{[\r\n]}{|} %throwable{separator(|)}%n />

Updated line 35 of log4j2.xml:
<PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss.SSS} %5p ${hostName} --- [%15.15t] %-40.40c{1.} correlation-id=%X{correlation-id} data-partition-id=%X{data-partition-id} api-method=%X{api-method} operation-name=%X{operation-name} user-id=%X{user-id} app-id=%X{app-id}:%m%replace{%m}{[\r\n]}{|} %throwable{separator(|)}%n />

High level design: Issue: Exception in stack trace is split across multiple lines causing too many logs. https://dev.azure.com/OpenEnergyPlatform/Open%20Energy%20Platform/_workitems/edit/6422

Test coverage:


  1. We tested the generated logs in IntelliJ Console and saw that the new lines are removed, and log size reduced.
  2. We tested on Kusto and Kusto is also not showing new lines.

Does this introduce a breaking change?
