MongoDB {autoIndexID,true} reports an error, why?

Question

Newbie, I just started learning MongoDB. When I created a collection, I used the command:
db.createCollection("mycol",{ autoIndexID: true })
Creation failed, prompt:

{
"ok" : 0,
"errmsg" : "The field 'autoIndexID' is not a valid collection option. Options: { autoIndexID: true }",
"code" : 72 ,
"codeName" : "InvalidOptions"
}
Even if it is changed to false, it will fail. But if you don't add this, you can succeed.

I want to know the reason, thank you God!

Answer 1

Read as many official documents as possible during the learning process. The content of many blogs is not rigorous:

autoIndexID --> autoIndexId

For reference.

Love MongoDB! Have Fun!
