set cassandre.trading.bot.exchange.modes.dry to false in src/main/ressources and try to run your bot again

[jechaviz]

cassandre.trading.bot.exchange.modes.dry=false same results

[jechaviz]

I tried with 5.0.8 and it gives me this detail: java.lang.NullPointerException: Cannot invoke "reactor.core.publisher.FluxSink.next(Object)" because "this.fluxSink" is null at tech.cassandre.trading.bot.util.base.batch.BaseFlux.emitValues(BaseFlux.java:67) at tech.cassandre.trading.bot.util.base.batch.BaseFlux.update(BaseFlux.java:76) at tech.cassandre.trading.bot.configuration.ScheduleAutoConfiguration.tickerFluxUpdate(ScheduleAutoConfiguration.java:94) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:77) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:568) at org.springframework.scheduling.support.ScheduledMethodRunnable.run(ScheduledMethodRunnable.java:84) at org.springframework.scheduling.support.DelegatingErrorHandlingRunnable.run(DelegatingErrorHandlingRunnable.java:54) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:539) at java.base/java.util.concurrent.FutureTask.runAndReset(FutureTask.java:305) at java.base/java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:305) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1136) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) at java.base/java.lang.Thread.run(Thread.java:833)

@jechaviz Can you try on another computer ? It's very strange as I don't have this problem on my computer and on my CI. Also, can you put the sources where I could download them and try by myself ? (REMOVE YOUR CREDENTIALS !))

[jechaviz]

You can download the source code from here: https://store5.gofile.io/download/e94507ce-b9d2-4726-bf71-a83dbcbfb6ca/LinnearChannelsBot.zip

Thank you.
