Fix Compatibility issue with MongoDB 6.0 #15

Open ahems opened 1 year ago

When I install MongoDb to my AKS cluster to use with this demo API using this command:

az aks command invoke --resource-group <myrg> --name <my cluster> --command "helm repo add bitnami https://charts.bitnami.com/bitnami && helm install ratings bitnami/mongodb --namespace ratingsapp --set auth.username=myusername,auth.password=mypassword,auth.database=ratingsdb"

I get this error thrown by the API when I try to call it using http://:3000/api/items

MongoError: Unsupported OP_QUERY command: find. The client driver may require an upgrade. For more details see https://dochub.mongodb.org/core/legacy-opcode-removal

The workaround for this issue is to use the previous version of MongoDB when deploying it for use by this code:

az aks command invoke --resource-group <myrg> --name <my cluster> --command "helm repo add bitnami https://charts.bitnami.com/bitnami && helm install ratings bitnami/mongodb --namespace ratingsapp --set image.tag=5.0.14-debian-11-r9,auth.username=myusername,auth.password=mypassword,auth.database=ratingsdb"
