Can you please describe a bit more in detail what "So I can't run DAG" means? Does it not start or do you get a specific error message? What I can tell is if the array field is empty, an empty array is treated as "None"/NULL Value and if you define the field as being array I assume it should complain that the (required, see a red start sign at the label) is missing a value. DAG should reject to be running as long as you don't enter at least one entry. Otherwise if you have a default value of `"[]"` I would expect that the string `[]` is used as default which is an array of one element with 1 string as default - which is more than NULL and represents one value, so is valid. Don't know if I mis-understand or if this is a race / corner case you hit. Either it is a mis-understanding or really a bug. I don't get it from the error description. -- This is an automated message from the Apache Git Service.
