Issue details

When I try to create a target group, I get an error which prevents the rest of my pulumi up command from working. I’m using version 4.25.0. I’ve tried dropping down many versions and they all produce the same errror.

Note that error only pops up intermittently. Most of the time, I will get the error, but in rare occasions (< 5% of the time) I don’t get an error.

Steps to reproduce

1. Start a new C# project with pulumi new aws-csharp
2. Create a new target group within the stack (this is an exerpt straight out of the samples but using Pulumi.Aws.LB instead of the deprecated Pulumi.Aws.ElasticLoadBalancingV2 (which also produces the same error)

using Pulumi;
using Ec2 = Pulumi.Aws.Ec2;
using Elb = Pulumi.Aws.LB;

class MyStack : Stack
{
    public MyStack()
    {
        // Read back the default VPC and public subnets, which we will use.
        var vpc = Output.Create(Ec2.GetVpc.InvokeAsync(new Ec2.GetVpcArgs { Default = true }));
        var vpcId = vpc.Apply(vpc => vpc.Id);
        var webTg = new Elb.TargetGroup("web-tg", new Elb.TargetGroupArgs
        {
            Port = 80,
            Protocol = "HTTP",
            TargetType = "ip",
            VpcId = vpcId
        });
    }
}

1. Run with pulumi up

Expected: Everything to run fine and the AWS target group should be generated

Actual:

Diagnostics:
  pulumi:pulumi:Stack (app-dev):
    error: Running program 'app.dll' failed with an unhandled exception:
    System.InvalidOperationException: Expected System.Double but got System.String deserializing Pulumi.Aws.LB.TargetGroup.deregistrationDelay

Ok folks, I have identified the issue here in our bridge code and a fix in on the way! I am sorry about this

Reproduced on my machine, can confirm that the deregistrationDelay property is coming back as a string from the provider. https://github.com/pulumi/pulumi/pull/8286 will provide a work around for this as long as deregistrationDelay isn’t actually used. There is also an underlying bug in the provider that we think this should be an int but it’s coming back as a string, I guess we need a shim to just call parseInt on the string returned from terraform.
