publish_continue_session() error

[grishaburd]

Hi, I am getting the following error massage when calling publish_continue_session() to clarify a slot (intent filter is set to a single intent). From the MQTT bus monitor, I can see that NLU gets the slot correctly filled, however due to error below my callback function is not being called. Any suggestions?
