Invalid request error while resizing managed database (MongoDB)

[bhwz-work]

Hello all,

We've run into a repeat error while attempting to apply a resize to a MongoDB managed database instance using this provider.

Error: Error resizing database cluster: PUT https://api.digitalocean.com/v2/databases/<id>/resize: 422 (request "<id>") error calculating additional storage size: failed to get plan disk range: rpc error: code = InvalidArgument desc = invalid request

For context the error started after attempting to move the database cluster into HA mode by setting node_count integer from 1 to 3. I initially thought it might be because we didn't define storage_size_mib after noticing it was set to 0 in our state, but setting the value to the default size for the slug we are using still returned the same error.

As a workaround we have manually resized the cluster from the DO web portal and reconciled the state.

I'm not quite sure if it's user error on our end (e.g. a missing or incorrect value somewhere) or a bug so I figured I'd run it past the community discussions first for some insight before potentially polluting the reports queue over on the issues tab.

Thanks!
