| Description | With the given process definition where an intermediate catch event message is used in a loop, we can get the following error under following circumstances. |
With the given process definition where an intermediate catch event message is used in a loop, we can get the following error under following circumstances:
* service tasks are set as {{asynchronous}}, * a service task fails because of a technical error. Retries will be done until the job is put as dead letter job. Once the job is put as dead letter job, if a service invocation is sent to submit the event, an error should occurs because no subscription is in progress but we get the following error: {code} org.flowable.engine.common.api.FlowableException: Query return 2 results instead of max 1 at org.flowable.engine.common.impl.AbstractQuery.executeSingleResult(AbstractQuery.java:165) at org.flowable.engine.common.impl.AbstractQuery.execute(AbstractQuery.java:145) at org.flowable.engine.impl.interceptor.CommandInvoker$1.run(CommandInvoker.java:51) at org.flowable.engine.impl.interceptor.CommandInvoker.executeOperation(CommandInvoker.java:93) at org.flowable.engine.impl.interceptor.CommandInvoker.executeOperations(CommandInvoker.java:72) at org.flowable.engine.impl.interceptor.CommandInvoker.execute(CommandInvoker.java:56) at org.flowable.engine.impl.interceptor.BpmnOverrideContextInterceptor.execute(BpmnOverrideContextInterceptor.java:25) at org.flowable.engine.common.impl.interceptor.TransactionContextInterceptor.execute(TransactionContextInterceptor.java:53) at org.flowable.engine.common.impl.interceptor.CommandContextInterceptor.execute(CommandContextInterceptor.java:72) at org.flowable.engine.common.impl.interceptor.LogInterceptor.execute(LogInterceptor.java:30) at org.flowable.engine.common.impl.cfg.CommandExecutorImpl.execute(CommandExecutorImpl.java:56) at org.flowable.engine.common.impl.cfg.CommandExecutorImpl.execute(CommandExecutorImpl.java:51) at org.flowable.engine.common.impl.AbstractQuery.singleResult(AbstractQuery.java:104) at org.ow2.petals.flowable.incoming.operation.IntermediateMessageCatchEventOperation.investigateMissingExecution(IntermediateMessageCatchEventOperation.java:192) at org.ow2.petals.flowable.incoming.operation.IntermediateMessageCatchEventOperation.doExecute(IntermediateMessageCatchEventOperation.java:134) at org.ow2.petals.flowable.incoming.operation.FlowableOperation.execute(FlowableOperation.java:211) at org.ow2.petals.flowable.incoming.FlowableJBIListener.onJBIMessage(FlowableJBIListener.java:144) at org.ow2.petals.component.framework.process.MessageExchangeProcessor.invokeJBIListener(MessageExchangeProcessor.java:525) at org.ow2.petals.component.framework.process.MessageExchangeProcessor.processAsProvider(MessageExchangeProcessor.java:493) at org.ow2.petals.component.framework.process.MessageExchangeProcessor.process(MessageExchangeProcessor.java:283) at org.ow2.petals.component.framework.process.MessageExchangeProcessor.run(MessageExchangeProcessor.java:181) at org.ow2.petals.component.framework.process.JBIProcessorThreadPoolExecutor$ExchangeRunnable.run(JBIProcessorThreadPoolExecutor.java:90) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) at org.ow2.petals.component.framework.process.JBIProcessorThreadFactory$JBIProcessorThread.run(JBIProcessorThreadFactory.java:99) {code} |

The problem is due to the investigation about the reason why no event subscription exists. A test accepts only one execution of the intermediate catch event per process instance but it can be executed several times in such use-cases with loop.
The investigation must be limited to:
