Hey @nemadroshan,

Are you using the Flowable Spring Boot starters or are you configuring your own engine configuration?

OK, that’s strange. This shouldn’t really happen.

Are you perhaps able to create a unit test or an example showing how we can reproduce this?

Hi @filiphr,

It’s the same error I’m getting in this topic: [Can't get HTTP Tasks to work in Flowable-rest docker](https://forum.flowable.org/t/cant-get-http-tasks-to-work-in-flowable-rest-docker/11435)

And my gut feeling is that it also has something to do with these:

> [@Flowable dynamic value in http task not working 6.8.0](https://forum.flowable.org/t/flowable-dynamic-value-in-http-task-not-working-6-8-0/10248/):

We were using this feature extensively in 6.7.2. I’ve created a simple example process that fails when setting the property to true. It succeeds when setting the property to false. \<?xml version="1.0" encoding="UTF-8"?\> \<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns…

Hey @nemadroshan,

Seems like we’ve found the root cause for this issue. It has been fixed in [Make sure DefaultAsyncTaskExecutor is started · flowable/flowable-engine@03d8680 · GitHub](https://github.com/flowable/flowable-engine/commit/03d8680cab866a55fb144d9d2d2b4b0f08c2a21e).

Cheers,  
Filip
