getting error response for the Update api - node.js

Question

I am new to this swagger and i created a small demo project in node-js to see how swagger will really works. I created 5 api's which 4 are working perfectly and when it comes to PUT api I am getting error ,but when i tried in postman it is working. Please look at the code below.
export let updateUser = async(req: Request, resp: Response) => {
try{
const use = await User.findById(req.params.id);
use.name = req.body.name;
// use.email = req.body.email;
const a1 = await use.save();
resp.json("successfully updated");
} catch(err) {
resp.send('Error')
}
}
this is the api which is calling above method in app.ts
//put-request
app.put('/user/update/:id',controller.updateUser);
This is the the swagger json of put API
"/user/update/{id}": {
"put": {
"tags": [
"Update-Api"
],
"summary": "Update-user",
"description": "To updatre the particular user",
"operationId": "updateUser",
"consumes": ["application/json"],
"parameters":[
{
"name":"Id",
"in":"path",
"description":"enter the id of the user",
"required":true,
"type":"string"
},
{
"name":"body",
"in":"body",
"description":"Enter the update value",
"required":true,
"$schema": {
"type": "#/definations/User"
}
}
],
"responses": {
"400": {
"description": "Invalid user supplied"
},
"404": {
"description": "User not found"
}
}
}
}

If you paste your API definition into https://editor.swagger.io, it will flag 2 syntax errors in the PUT operation. Make sure to fix these errors before testing your API.
In the parameter definition, change "name":"Id" to "name":"id" (lowercase id) to match the parameter letter case in the path template.
In the body parameter, change $schema to schema.
