aws-opensearchservice: Creating a domain fails for vpc/subnets in the pipeline

### Describe the bug

I'm moving CDK app to the pipeline.
For unknown reason the vpc property returns only 2 subnets (in form of unresolved tokens), for Domain construct.
This stack was deployed before, now it is a stage

So when I use this property in OPENSEARCH.Domain, cdk can't compile templates
```
zoneAwareness: {
availabilityZoneCount: 3,
}
```

### Expected Behavior

cdk can compile properly

### Current Behavior

```
cdk synth

Error: When providing vpc options you need to provide a subnet for each AZ you are using

```

### Reproduction Steps

Plain vanilla VPC + OPENSEARCH.Domain + CDK Pipelines (sorry can't provide actual example since CDK app structure is pretty custom). However, VPC props is standard

```
{
ipAddresses: EC2.IpAddresses.cidr('10.0.0.0/16'),
natGateways: 1,
maxAzs: 3,
subnetConfiguration: [
{
cidrMask: 24,
name: 'ingress',
subnetType: EC2.SubnetType.PUBLIC,
},
{
cidrMask: 24,
name: 'application',
subnetType: EC2.SubnetType.PRIVATE_WITH_EGRESS,
},
{
cidrMask: 24,
name: 'rds',
subnetType: EC2.SubnetType.PRIVATE_ISOLATED,
},
],
}

```

### Possible Solution

Can't find any

### Additional Information/Context

Tried with latest cdk versions as well.

### CDK CLI Version

2.65

### Framework Version

2.65

### Node.js Version

v16.17.0

### OS

Mac OSX

### Language

Typescript

### Language Version

"typescript": "^4.6.3"

### Other information

_No response_

Start by reproducing `cdk synth` with the listed VPC configuration, CDK Pipelines, and an OpenSearch Domain using three availability zones. Read `lib/constructs/openSearchConstruct.ts:26` and the stack entry at `lib/stacks/index.ts:160` alongside the reported aws-opensearchservice validation. Done means the pipeline stack synthesizes successfully with the three-AZ VPC configuration.
