uniapp WebView 的@error会返回什么数据

uniapp WebView 的@error会返回什么数据我目前接到的数据是

{
"type": "error",
"timeStamp": 1762579826792,
"target": {
"id": "",
"dataset": {},
"offsetLeft": 0,
"offsetTop": 0
},
"currentTarget": {
"id": "",
"dataset": {},
"offsetLeft": 0,
"offsetTop": 0
},
"detail": {
"errorMsg": "ssl error",
"type": "error"
},
"stopPropagation": "function() { [native code] }",
"preventDefault": "function() { [native code] }"
}
我想知道 "detail": {
"errorMsg": "ssl error",
"type": "error"
},里的errorMsg还会返回什么
