Duplicate key in session when using different browser on same machine

[herzcthu]

I got this response on second browser when trying to open my newly setup laravel app. E11000 duplicate key error collection: pace.sessions index: id_1 dup key: { id: null }

I'm using latest laravel 8. laravel-mongodb 3.8 laravel-mongodb-session 1.4

I'm just trying to setup my new project with mongodb support. This is composer.json

same problem too

Hi All, I had this same problem - take a look at the specific message: index: id_1 dup key: { id: null }

Note that index is "id_1" and it's complaining that the id is null.

I found that my sessions table had 3 indexes: "_id", "id_1", and "last_activity". You can see your indexes with: db.sessions.getIndexes()

I think that "id_1" has been added in error - maybe during the Laravel upgrade to v7 or v8 or when switching session support on from file-based to database.

So the simple job is to remove the "id_1" key: db.sessions.dropIndex("id_1")

It's now all working for me.
