TypeError: Cannot read property 'listDatabases' of undefined

I updated my mongo-express kubernetes deployment to arm64v8/mongo-express:0.54 yesterday.

Since then, I got this error message :

Admin database is not accessible

I'm connecting to a mongodb statefulset of 3 replicas. It worked before update (I don't remember which version was working before this one).

My deployment.yaml looks like this
