If you right click on a workflow and select "View OpenAPI" you will get the required documentation

Hi, is it possible to send/attach the workflow?

Hi, this doesnt have to do with prefetch count. It seems that when processing a queue item that takes a long time to run. The unack times out. This is something i am investigating on another open ticket

I don't see what the problem is here. Based on the screenshots everything looks ok?

Not a bug. As discussed in meeting. There is a special character coming from the supplied data

Fixed in version 2.7.9
