pulumi-gcp: Error 412 while updating gcp.sql.DatabaseInstance

What happened?

I’m attempting to enable the High Availability setting for an existing GCP Postgres SQL instance. Adding the availability type parameter returns the following error

  pulumi:pulumi:Stack (app):
    error: update failed
 
  gcp:sql:DatabaseInstance (db-server):
    error: 1 error occurred:
    	* updating urn:pulumi:test::app::gcp:sql/databaseInstance:DatabaseInstance::db-server: 1 error occurred:
    	* Error, failed to update instance settings for : googleapi: Error 412: Condition does not match., staleData

Steps to reproduce

Create a DB instance

export const dbInstance = new gcp.sql.DatabaseInstance("db-server", {
  databaseVersion: "POSTGRES_11",
  region: "us-central1",
  settings: {
    tier: "db-g1-small",
    diskAutoresize: false,
    backupConfiguration: {
      enabled: false,
      location: "us-central1",
      pointInTimeRecoveryEnabled: false,
      startTime: "01:00",
      transactionLogRetentionDays: 7,
      backupRetentionSettings: {
        retainedBackups: 14,
      },
    },
    userLabels: {
      "env": "test",
    }
  },
  deletionProtection: false,
});

Add availabilityType to the instance settings

export const dbInstance = new gcp.sql.DatabaseInstance("db-server", {
  databaseVersion: "POSTGRES_11",
  region: "us-central1",
  settings: {
    tier: "db-g1-small",
    diskAutoresize: isProduction,
    availabilityType: "REGIONAL",
    backupConfiguration: {
      enabled: false,
      location: "us-central1",
      pointInTimeRecoveryEnabled: false,
      startTime: "01:00",
      transactionLogRetentionDays: 7,
      backupRetentionSettings: {
        retainedBackups: 14,
      },
    },
    userLabels: {
      "env": "test",
    }
  },
  deletionProtection: false,

Run pulumi up

Expected Behavior

The existing GCP SQL database instance availability is changed from ZONAL to REGIONAL.

Actual Behavior

The update fails and returns the error above. The following data was also in the logs:

Versions used

Pulumi version: 3.29.1

Additional context

Adding anything appears to trigger the error, including explicitly entering the default value availabilityType: "ZONAL"
