Symptoms

5G Charging Function (CHF) is sending empty trigger elements in N40 response to Session Management Function (SMF), These empty trigger elements can disable the triggers at SMF end if SMF is configured to follow CHF trigger field.
 

The CHF may enable one or more triggers at the NF consumer, by including them in the Triggers element. The omitted triggers in the Triggers element shall be interpreted by the Network Function (NF) consumer as disabled. The enabled and disabled triggers setting at the NF consumer shall remain in effect until another Triggers element is received from the CHF for the service session or rating group. When the NF consumer receives a Triggers element it shall enable all triggers present in the Triggers element and disable all other triggers at the same level. The presence of the Triggers element without any trigger type in a response message allows CHF to disable all the triggers at the NF Consumer for service session or rating group.

This is violation of " 3GPP TS 32.291 version 16.5.1 Release 16 section 6.2.5.2.1.2 Type ChargingDataResponse"
