Cannot run flow in corda node

I am running a corda network on kubernetes (corda version 4.4) and I am trying to install and run a cordapp .

The cordapp am trying to run is the Heartbeat one (from the github corda sample folder) .

But whenever I try to start the flow using the command start StartHeartbeatFlow

I get the following error message : 

[INFO] 11:00:32+0200 [pool-2-thread-11] shell.StartShellCommand.main - Executing command "start StartHeartbeatFlow <no arguments>",
start StartHeartbeatFlow: exception: com.heartbeat.StartHeartbeatFlow
Tue Apr 07 11:00:32 CEST 2020>>> [ERROR] 11:00:32+0200 [pool-2-thread-11] command.CRaSHSession.execute - Error while evaluating request 'start StartHeartbeatFlow' start StartHeartbeatFlow: exception: com.heartbeat.StartHeartbeatFlow [errorCode=1oe81or, moreInformationAt=https://errors.corda.net/OS/4.4/1oe81or]

Which doesn't really help me on how to solve the issue :/

Running flow list is listing the StartHeartbeatFlow so it's not an issue with the installation of the cordapp ...

Has anyone encountered the same kind of issue ?

Thanks !

Edit : The logs in the corda node I have when I execute the flow start StartHeartbeatFlow command .

I could invoke the flow from the standalone shell , I was having some weird issues with the /cordapp folder holding my cordapp locally . I deleted it and recreated it and now it works .

Can you update your question with more stack trace? Are there any other errors in your node's log file? I'm asking because I just tried the example and it worked for me.

Here's what I did:

  1. Built the Java version: 
// Browse to Java files.
cd /heartbeat/contracts-java

// Build the nodes (Notary and PartyA).
./../gradlew deployNodes
  1. Start the nodes (I don't like using runnodes task, so I start each node individually):
// Terminal 1 (Notary).

cd /heartbeat/contracts-java/build/nodes/Notary
// Start the Notary.
java -jar corda.jar

// Terminal 2 (PartyA).

cd /heartbeat/contracts-java/build/nodes/PartyA
// Start PartyA.
java -jar corda.jar
  1. Start the flow inside of PartyA's terminal. Notice that I use flow start instead of just start (like in your case); it's worth trying flow start, even though both should work:
flow start StartHeartbeatFlow
  1. You will see in my screenshot below that the flow completed (i.e. it created the SchedulableState that will start the flow again, which will lead to an endless loop until you shutdown the node):

Start Flow

  1. Now I can watch that flow being called again and again by typing the below in PartyA's terminal:
flow watch

Watch Flow
