How to import existing VPC in aws cdk

Question

Hi I am working on aws cdk. I am trying to get existing non-default vpc. I tried below options.

vpc = ec2.Vpc.from_lookup(self, id = "VPC", vpc_id='vpcid', vpc_name='vpc-dev')

This results in below error

[Error at /LocationCdkStack-cdkstack] Request has expired.
[Warning at /LocationCdkStack-cdkstack/TaskDef/mw-service] Proper policies need to be attached before pulling from ECR repository, or use 'fromEcrRepository'.
Found errors

If your VPC is created outside your cdk app you can use Vpc.formLookup(). The CDK CLI will search for the specified VPC in the stack's region and account and import the subnet configuration. Looking up can be done flexibly by searching for a specific tag.
