I’m getting the “Request to Webtask exceeded allowed execution time” error when trying to use a custom database with mongodb. I’ve downloaded the [Real Time Webtask Logs](https://auth0.com/docs/extensions/real-time-webtask-logs) extension and I keep getting a UnhandledPromiseRejectionWarning with the message TypeError [ERR\_INVALID\_ARG\_TYPE]: The “url” argument must be of type string. Received undefined. I think it’s because I’ve been trying to use the configuration variables for database settings; I currently have a key DB\_URL set to my database’s URL. I have tried putting the URL in quotations and not in quotations and both times I get the same error. Everything else I have been using the default mongodb template that auth0 has provided. EDIT: Forgot to mention, but I had to delete the @3.1.4 from require(‘mongodb’). ---

Ok, now it seems like the issue is with the connection string. I think auth0 might be using an older version of MongoClient that only accepts connection strings that start ONLY with mongodb://. However, this isn’t possible for me as I need the mongodb+srv:// starter. Any help would be appreciated. ---

It’s likely the default version used when you do `require('mongodb')` is old and doesn’t support the scheme. It should work with 3.1.4 though - any particular reason you deleted the `@3.1.4` part? The available NPM module versions in custom DB scripts can be found here: [https://auth0-extensions.github.io/canirequire/#mongodb](https://auth0-extensions.github.io/canirequire/#mongodb) I would encourage pinning the version with an `@` since the default version can change in the future causing the script to potentially break. ---

When using the 3.1.4 part, I would get the error “The server is being accessed through a load balancer, but this driver does not have load balancing enabled” ---

Using mongodb@4.1.0 fixes things. ---
