This issue refers to field eventFilters under eventTrigger of CloudFunction type, referenced here:

With the current implementation, there's no eventFilters available to pass to the action to make it work with triggers other than Pub/Sub. Other triggers like GCS require specific filters in use in order to properly work when deploying using GEN_2 functions. This makes the action fail with an error like this:

"error": ***
    "code": 400,
    "message": "Validation failed for trigger projects/**project**/locations/**location**/triggers/******: The request was invalid: missing required attribute \"bucket\" in trigger.event_filters",
    "status": "INVALID_ARGUMENT"
  ***
***

Is it possible to use the action to deploy a Gen2 function being triggered by a GCS bucket event like google.storage.object.finalize or should we fall back to use gcloud deploy instead?
