Azure Function and SharePoint PnP PowerShell are mixing up the client context

Hi,

I'm experimenting with Azure Function, Logic apps/Flow to replace an existing SharePoint Workflow.

I've found a weird issue where the client context get mixed up when multiple flows are running in parallel and try to call the azure function. I've found a workaround to overcome this issue by allowing only one job on the azure function environment. It's not a good solution, therefor I want to find the root cause of the following error message :

Exception calling "Load" with "1" argument(s): "The object is used in the context different from the one associated with the object."

Has someone encounter a similar issue?

Cheers 

Bernd
