Hi! I'm trying to call a child flows and I got the error.

"Update the child flow so the 'Execute_a_Child_Flow' action does not use "execution-only user" connections."

The problem is that I dont Have a 'Run-Only-User" as this.

Could anyone help me?

The "Run-Only User" would only support in the flow with trigger "Manually trigger a flow" or "For a selected item",
Can you check what is your flow trigger, is it manually trigger flow?

Hi @anacarolinagr

When you call a flow as child flow then you need to provide a static or fixed connections for all connectors used in that flow. As by default in manual flow, connections are configured as "provided by run only user" so we need to provide fixed connections for all of those connectors.

Here is an example of how-to set explicit connections for connectors in child flow:

Go to flow details page, scroll down to "Run only users" section and click "Edit" button next to it:

Now, scroll down to "Connection used" section where you can see all the connectors used in the flow:

Select the fixed connection from the drop down and save it.

After making explicit connections in child flow, parent flow won't throw error anyone when calling the child flow.

If this helps & solves your problem, please remember to give a 👍 and accept my solution as it will help others in the future.

Thanks
