Hello, I'm trying to troubleshotting a stack update. Every time when I run
Copy code
pulumi update
the process want to update my resource (db-instance) on my gcp even when diff operations shows that everything are the same. When I use
Copy code
pulumi update --diff --json > diff-file.json
I can see the newState and oldState for resource is exactly the same but pulumi still want to update it with error like this:
Copy code
... 1 error occurred:
        * Error, failed to update instance settings for : googleapi: Error 412: Condition does not match., staleData
Could anyone advice me how I could track it down?
