Hey all, We recently updated azure-classic (golang) from v4 to v5 (for Azure AKS container service) and as a result of this, we now get the following error: panic: interface conversion: interface {} is nil, not []interface {} goroutine 183 [running]: github.com/hashicorp/terraform-provider-azurerm/internal/services/containers/migration.KubernetesClusterV1ToV2.UpgradeFunc.func1({0x7f39168?, 0xc0033fcb10?}, 0x6c0bac0?, {0xc0034b0240?, 0x7f39168?}) /home/runner/go/pkg/mod/github.com/pulumi/terraform-provider-azurerm@v1.41.1-0.20221210195015-5fc8f8c607aa/internal/services/containers/migration/kubernetes_cluster.go:1231 +0x2fe github.com/hashicorp/terraform-provider-azurerm/internal/tf/pluginsdk.StateUpgrades.func1({0x7f36538, 0xc00012e030}, 0x2?, {0x6ba2ca0, 0xc0019f5400}) /home/runner/go/pkg/mod/github.com/pulumi/terraform-provider-azurerm@v1.41.1-0.20221210195015-5fc8f8c607aa/internal/tf/pluginsdk/state_upgrades.go:52 +0x64 github.com/hashicorp/terraform-plugin-sdk/v2/helper/schema.UpgradeJSONState({0x7f36538, 0xc00012e030}, 0x0?, 0xc0033dbe60?, 0xc000e1ee00?, {0x6ba2ca0, 0xc0019f5400}) /home/runner/go/pkg/mod/github.com/pulumi/terraform-plugin-sdk/v2@v2.0.0-20220824175045-450992f2f5b9/helper/schema/grpc_provider.go:449 +0xa7 github.com/pulumi/pulumi-terraform-bridge/v3/pkg/tfshim/sdk-v2.upgradeResourceState(0xc00012bec0, 0xc000a74540?, 0xc0025fdc70) /home/runner/go/pkg/mod/github.com/pulumi/pulumi-terraform-bridge/v3@v3.30.0/pkg/tfshim/sdk-v2/upgrade_state.go:44 +0x205 github.com/pulumi/pulumi-terraform-bridge/v3/pkg/tfshim/sdk-v2.v2Provider.Diff({0xc000250f00?}, {0x76f67c5, 0x1a}, {0x7f3b200?, 0xc003464950}, {0x7f26da0, 0xc003443c20}) /home/runner/go/pkg/mod/github.com/pulumi/pulumi-terraform-bridge/v3@v3.30.0/pkg/tfshim/sdk-v2/provider.go:102 +0x17a github.com/pulumi/pulumi-terraform-bridge/v3/pkg/tfbridge.(*Provider).Diff(0xc000250f00, {0x7f365a8?, 0xc0033db080?}, 0xc0033d68c0) /home/runner/go/pkg/mod/github.com/pulumi/pulumi-terraform-bridge/v3@v3.30.0/pkg/tfbridge/provider.go:763 +0x571 github.com/pulumi/pulumi/sdk/v3/proto/go._ResourceProvider_Diff_Handler.func1({0x7f365a8, 0xc0033db080}, {0x70ff060?, 0xc0033d68c0}) /home/runner/go/pkg/mod/github.com/pulumi/pulumi/sdk/v3@v3.40.3-0.20220928152524-977c89fcacd7/proto/go/provider.pb.go:3728 +0x78 github.com/grpc-ecosystem/grpc-opentracing/go/otgrpc.OpenTracingServerInterceptor.func1({0x7f365a8, 0xc0033da810}, {0x70ff060, 0xc0033d68c0}, 0xc0025c9cc0, 0xc0025afae8) /home/runner/go/pkg/mod/github.com/grpc-ecosystem/grpc-opentracing@v0.0.0-20180507213350-8e809c8a8645/go/otgrpc/server.go:57 +0x3f9 github.com/pulumi/pulumi/sdk/v3/proto/go._ResourceProvider_Diff_Handler({0x73a1ac0?, 0xc000250f00}, {0x7f365a8, 0xc0033da810}, 0xc0033d6850, 0xc000348060) /home/runner/go/pkg/mod/github.com/pulumi/pulumi/sdk/v3@v3.40.3-0.20220928152524-977c89fcacd7/proto/go/provider.pb.go:3730 +0x138 google.golang.org/grpc.(*Server).processUnaryRPC(0xc00035e000, {0x7f4ac00, 0xc001aa9d40}, 0xc003381c20, 0xc00034c3f0, 0xd58e688, 0x0) /home/runner/go/pkg/mod/google.golang.org/grpc@v1.50.1/server.go:1340 +0xd23 google.golang.org/grpc.(*Server).handleStream(0xc00035e000, {0x7f4ac00, 0xc001aa9d40}, 0xc003381c20, 0x0) /home/runner/go/pkg/mod/google.golang.org/grpc@v1.50.1/server.go:1713 +0xa2f google.golang.org/grpc.(*Server).serveStreams.func1.2() /home/runner/go/pkg/mod/google.golang.org/grpc@v1.50.1/server.go:965 +0x98 created by google.golang.org/grpc.(*Server).serveStreams.func1 /home/runner/go/pkg/mod/google.golang.org/grpc@v1.50.1/server.go:963 +0x28a After some digging, we see the code that fails in the screenshot. Has anyone ran into this issue before? Know of workaround(s)?

please open an issue

actually was able to fix it

Awesome Andre!
