any idea what causing this? i am using pulumi.random and the result of that is

DFpSfUijK8

error: deleting urn:pulumi:dev::allrites-infrastructure::custom:component:rds:globaldb$aws:rds/cluster:Cluster::globaldb-cluster: 1 error occurred:

How are you using pulumi.random? Maybe you're using the Output as a string?

This is how i am using the random

const finalSnapshotIdentifier = new random.RandomString("final-snapshot-identifier-random", {
   length: 10,
   special: false,
 }).result

----
{
  finalSnapshotIdentifier: config.get<string>('FINAL_SNAPSHOT_IDENTIFIER') || finalSnapshotIdentifier,
}

That's an interesting one. The type of that is

string || pulumi.Output<string>

which possibly isn't being resolved as a

pulumi.Output<string>

, so you're ending up with the error message (the one that says you cannot use an Output as a string) as the finalSnapshotIdentifier. To confirm / work around this, you could change the value to this:

{
  finalSnapshotIdentifier: pulumi.output(config.get<string>('FINAL_SNAPSHOT_IDENTIFIER') || finalSnapshotIdentifier)
}

This will definitely be detected as a

pulumi.Output

, so it should sort itself out. If it doesn't, then the next thing to do is to look at the actual value by logging. Something along the lines of

<http://pulumi.log.info|pulumi.log.info>(`Config value: ${config.get<string>('FINAL_SNAPSHOT_IDENTIFIER')}`);
<http://pulumi.log.info|pulumi.log.info>(("Random string", finalSnapshotIdentifier);

Note that you have to use the two-parameter version of pulumi.log.info() or else put that log statement inside an apply().
