WS20000050 - Custom rule in step 372 - Error during execution

I have attached a custom rule in Step 372 of workflow WS20000050

WS20000050 works fine with standard rule (168)

Custom rule is tested and simulated and it returns the Person 'P' and User 'US'

WS20000050 genarates fine with no errors (4 information only)

Errors after execution in SWIA is

Error when processing node '0000000372' (ParForEach index 000000)
Error when creating a component of type 'Step'
Error when creating a work item
Agent determination for step '0000000372' failed
Error in resolution of rule 'AC92000002' for step '0000000372'
Element OBJID is not available in the container

next node in error

Work item 000000426198: Object FLOWITEM method EXECUTE cannot be executed
Error when processing node '0000000372' (ParForEach index 000000)

I tried to delete OBJID from the binding for the rule but the same error repeats

Any help is appreciated
