This is causing the test (fake) errors to leak to `stdout`. Something like this should do the trick: ``` appender.out.type = File appender.out.name = out appender.out.fileName = target/camel-wasm-test.log appender.out.layout.type = PatternLayout appender.out.layout.pattern = %d [%-15.15t] %-5p %-30.30c{1} - %m%n appender.stdout.type = Console appender.stdout.name = stdout appender.stdout.layout.type = PatternLayout appender.stdout.layout.pattern = %d [%-15.15t] %-5p %-30.30c{1} - %m%n rootLogger.level = WARN rootLogger.appenderRef.out.ref = out logger.camel.name=org.apache.camel logger.camel.level=INFO logger.camelWasm.name=org.apache.camel.component.wasm logger.camelWasm.level=DEBUG ``` -- This is an automated message from the Apache Git Service.
