Is the only option to create VPC endpoints within

apply()

when using this code?

# vpc endpoints
        vpc_endpoints = ["s3", "ecr.dkr", "ecr.api", "logs"]
        region_output = self._config.aws_provider.region
        for endpoint in vpc_endpoints:
        
            service_name = region_output.apply(
                        lambda region: f"com.amazonaws.{region}.{endpoint}"  # endpoint here does not update from the loop variable
                    )
            pulumi_aws.ec2.VpcEndpoint(
                f"{self._config.name}-{endpoint}-vpc-endpoint",
                args=pulumi_aws.ec2.VpcEndpointArgs(
                    service_name=service_name,
                    vpc_id=self.vpc.id,
                    tags=self._config.tags,
                ),
                opts=self._opts,
            )

you shouldn't need to use an apply because you're passing outputs (vpc.id) from the vpc object

vpc.id

is not a problem, the problem comes from the

region

assigned in

svc = ...
