Error during pulumi import : Go provider for GCP on Importing routerNat

[maikeffi]

Expected behavior

When trying to import RouterNat of GCP
pulumi import gcp:compute/routerNat:RouterNat

Import Completes successfully and a sample code of the imported resource is expected
But got the error below in

Current behavior

Below is the output log

Steps to reproduce

1. create a go gcp pulumi project
2. login to gcs to maintain state
3. run command pulumi import gcp:compute/routerNat:RouterNat <path to gcp nat rounter with name>
4. Import Completes successfully
5. above error is encountered when generating sample code .

Context (Environment)

We are trying to set up pulumi for an existing gcp environment .

Affected feature

pulumi import , Code generation
