Hello,

At final step "Using a Trained Brain" of Bonsai tutorial, the query to server was success, but response value didn't write to Actions parameter table.

Value of "NextType" didn't changed in Actions parameter table.

Thank you for reporting this bug. I'm not sure if we'll release another version of the beta, or if we'll go straight to the 2023 release, but the fix will be in either version.

The issue is caused by this node: MAIN:/project/library/ReinforcementLearning>behaviour/eventfunctions/bonsaiSettings/logMessages/takeAction

Because there's a node named "takeAction" inside the eventfunctions node, it prevents the takeAction function_s from being called.

To work around this issue, try renaming that node to "_takeAction". It should work correctly, although you may notice a slight change in the text shown when running an unmanaged simulator.
