Expected Behavior
As in previous ocassions, the map runs without issues (well, we were having the timeout sometimes, but this is new).
Steps to reproduce
Used the MMUX service to run the map_function of the functions API.
Environment
sim4life-staging.cloud
Additional context
I just registered this function through the frontend - but I have already done so previously and did not have this issue.
