ViewsMongoServerError: Cannot create field 'count' in element
When the database matches the below value then I want to increase the count by 1.
const inr = await Postproduct.updateOne({"uid":123456,"userclick.email":"neelshah486@gmail.com"},{$inc: { "userclick.count": 1}})But right now I'm getting the following error while doing so.
And this is my database
Kindly help me with the same. What I want to do is every time the user clicks the button. I want the count to increase by 1.

Since userclick is an array, you will need to use an array operator for updating just the one element.
In this case, since the query uniquely identifies one element, you can use the $ positional operator, like:
await Postproduct.updateOne(
{"uid":123456,"userclick.email":"neelshah486@gmail.com"},
{$inc: { "userclick.$.count": 1}}
)

You can set default value of count to zero. like this :
userClicks:[{
count:{type:Number,default:0,},
email:String,
satisfy:String,
amount:Number,
}]
