Question

Any reason why a microflow called by CommunityCommons.executeMicroflowInBackground would not get executed?

I have a microflow, call it SUB_Child, that I call using CommunityCommons.executeMicroflowInBackground. The parent microflow, call it SUB_Parent, was ended but SUB_Child never was executed and I don't see any errors. What could've happened?

One of the reasons is too many microflows are queued to run in the background. Community Commons uses Core.executeAsync under the hood and that silently discards microflows after some limit (at least in Mendix 9). Mendix did not consider it a bug in 2022. The max queue size was 200.

To make sure try to execute 300 long running microflows and see how soon they're discarded.
