Hi. 

I think something is going not completely right with the systemflow. Why does the scheduling keep ending up in an error. It's generating big log-files.

It seems it can connect to the IAM database but when trying to execute the system flows on the SF it fails.
Can you double check if the server for the gui appl 5 (SF) is correctly configured in IAM?

I checked and it as filled in as develop_server, which I guess is the default after installing the IAM + SF.

I changed it to local host. Is there a way to force system flow to run outside of it's scheduled time? 

Hello Freddy,

You can manually trigger a system flow through Indicium's API:

POST
/indicium/iam/appl/<process_flow_id>

I hope this helps.

You can force a system flow by doing a post request with Insomnia to its endpoint. But in this case it is easier to just go to: `<url>/iam/sf/project` to see if it can load some data from the project table.

If you see some projects then the System flows will also be able to connect as they use the same settings.

Hi @Freddy,

Did @Dick van den Brink answer your question or do you need more help with this?
