Node-red crash after installing unified red

On fresh new instalation of node-red, (just add unified-red pallette)

After installing unified-red node-red crash after this message :

[error] MongooseError: Operation `roles.findOne()` buffering timed out after 10000ms

at Timeout.<anonymous> (/Users/USERNAME/.node-red/node_modules/unified-red/node_modules/mongoose/lib/drivers/node-mongodb-native/collection.js:198:23)

I saw the “Error after installing unified-red” with the same issue, but in my case it’s appear even before instaling mongodb

Any idea

Thank for your help
