post ai.dial报错了Invalid request or non-existant command

[fengyh13]

我使用nodejs请求AIAPI,请求参数是： got post application/json
{
jsonrpc: '2.0',
method: 'ai.dial',
id: 1706280989320,
params: {
application: 'ai',
dial_string: "{leg_timeout=30,execute_on_answer='sched_hangup +10'}user/1004",
from: '1005',
url: 'http://xxx:1233',
external_tracking_id: '1706280989320',
private_data: { param1: '1', seq: '2' }
}
}
返回错误信息：
{
"jsonrpc": "2.0",
"error": {
"code": -32600,
"message": "Invalid request or non-existant command"
},
"id": 1706280989320
}
调试的阿里的TTS/ASR都已经通了，http请求报错了，请问是哪里错了
