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/):

> Since upgrading to 6.8 we aren’t able to call HTTP tasks in true parallel with the “execute parallel in same transaction” property. Is this a known bug? 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…
