Comyfy UI API validation Error

### Custom Node Testing

- [ ] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

i want use call run workflow api in dify comfyui. dify is a ai based workflow editor.

i export and copy workflow json to dify and make a template to replace some variables in run time.

### Actual Behavior

i always get this validate error, when using api execute workflow

```shell
To see the GUI go to: http://0.0.0.0:8188

```
in this node are 4 arguments, and fully defined in UI

and i checked the exported json file
```json
{
"id": 41,
"type": "InitMinioConnector|Mie",
"pos": [
2440.582521738089,
-319.1391509006392
],
"size": [
330,
130
],
"flags": {},
"order": 11,
"mode": 0,
"inputs": [
{
"name": "secure",
"type": "BOOLEAN",
"widget": {
"name": "secure"
},
"link": 76
}
],
"outputs": [
{
"name": "minio_connector",
"type": "MINIO_CONNECTOR",
"links": [
69
]
}
],
"properties": {
"cnr_id": "comfyui_minioconnector",
"ver": "1.0.7",
"Node name for S&R": "InitMinioConnector|Mie"
},
"widgets_values": [
"192.168.31.88:9050",
"some_key",
"some_secrect",
false
]
},
```
in widgets_values the false value should be secure ,but run api are export error.

### Steps to Reproduce

this is the template json,and below and below also have translated workflow
