I've tried to have decor plants to yield a fruit (most of them are metal ores) but it seems like it's not working. The code pass the check on starting the game but crash when it's loading into the map here's an example of my code;

{
"id": "PrickleGrass",
"disease": "PollenGerms",
"disease_amount": 10000,
"fruitId": "CopperOre",
"fruit_grow_time": 2400.0,
"fruit_amount": 40,
"irrigation": {
"Water": 10.0
},
"output_element": "Oxygen",
"output_rate": 0.001
},


Not sure which sentence is the problem. Please kindly enlighten me. Thank you in advance.
