Hello everyone!
Maybe someone can help me:
I'm trying to run the Run a Child Flow action, but I always get the error: "The server did not receive a response from an upstream server."
Both flows are in the same solution, the parent flow sees the child flow and I can select it, but in the execution I do not get a response.
I already made the change in the "Run Only Users" option.

Thanks in advance for any suggestions.
