I tried

pulumi stack import --file dev.checkpoint.json

It's a checkpoint file i edited I got following error after wanting to pulumi preview: error: .pulumi/stacks/dev.json: snapshot integrity failure; refusing to use it: resource urnpulumidev:lsdigitaloceanindex/kubernetesClusterKubernetesCluster:staging refers to unknown provider urnpulumidev:lspulumiprovidersdigitaloceandefault 1 6 0:*charactersequence* I am positive i did not change "provider" and that cluster is still running on DO cloud. Does anyone have an idea what I might've done wrong or how i can fix this?
