conductor Null Pointer Exception results in a flow which cannot be actioned (terminated etc)

Null Pointer Exception results in a flow which cannot be actioned (terminated etc)

Open azriel46d opened this issue 1 year ago • 2 comments

Describe the bug We have a flow which from what I'm seeing in the definition has a WAIT task with an invalid external storage path. This results in a null pointer exception whenever trying to terminate the flow or do any additional action on it.

Details Conductor version: 3.10.2 Persistence implementation: Postgres Queue implementation: Postgres

Expected behavior Below is the exception when trying to execute the POST /api/tasks , this is the same error for attempting to terminate the flow and it happens also on the underlying seeper

@azriel46d What is the external payload storage configuration that you are using? Please provide details about the type and the configured values for the thresholds.

Aug 08 '22 17:08 apanicker-nflx

Utilising postgres and elastic. here is the configuration

conductor.grpc-server.enabled=false

# Database persistence model.
conductor.db.type=postgres

spring.datasource.url=jdbc:postgresql://postgresql:5432/conductor-test
spring.datasource.username=xxxxxx
spring.datasource.password=xxxxxx

# Hikari pool sizes are -1 by default and prevent startup
spring.datasource.hikari.maximum-pool-size=10
spring.datasource.hikari.minimum-idle=2

# Elastic search instance indexing is enabled.
conductor.indexing.enabled=true

# Transport address to elasticsearch
conductor.elasticsearch.url=http://es:9200


# Name of the elasticsearch cluster
conductor.elasticsearch.indexName=conductorpersist

# By default with dynomite, we want the repairservice enabled
conductor.app.workflowRepairServiceEnabled=false


conductor.elasticsearch.indexReplicasCount=0
conductor.elasticsearch.clusterHealthColor=yellow
loadSample=false

@azriel46d It looks like you are using the default implementation which returns null. We have identified this as a missing case in our testing and will push out a release soon. Thank you for reporting.

This has been fixed in v3.10.7

Aug 22 '22 21:08 apanicker-nflx

Although most flows can be terminated with the above fix. I still have one which cannot be terminated giving the following error
