Doing a `pulumi destroy` results in the same error message when it fails to load the plugin ``` error failed to load resource plugin aws failed to perform plugin load callback failed to save snapshot after mutation of snapshot resource urn pulumi pulumi subnets test dev pulumi subnets test operator error aws Vpc$aws ec2 vpc Vpc$aws ec2 subnet Subnet$aws ec2 routeTableAssociation RouteTableAssociation demo public rta 1 dependency urn pulumi pulumi subnets test dev pulumi subnets test aws ec2 vpc Vpc$aws ec2 routeTable RouteTable demo public rt refers to missing resource ```

This gets a bit gross you re going to need to export the stack s checkpoint edit it manually to remove the offending dependency and import the repaired checkpoint

microscopic-florist-22719 · Answer

The export is performed by incanting `pulumi stack export` This will dump the checkpoint to `stdout` so you ll want to redirect to a file

microscopic-florist-22719 · Answer

The checkpoint is exported as JSON so I usually do something like `$ pulumi stack export gt d json`

microscopic-florist-22719 · Answer

Once you have the exported checkpoint in hand it is probably sufficient to search for `urn pulumi pulumi subnets test dev pulumi subnets test aws ec2 vpc Vpc$aws ec2 routeTable RouteTable demo public rt` If my guess is correct and it certainly may not be you ll find a single reference to this resource in the dependency list for `urn pulumi pulumi subnets test dev pulumi subnets test operator error aws Vpc$aws ec2 vpc Vpc$aws ec2 subnet Subnet$aws ec2 routeTableAssociation RouteTableAssociation demo public rta 1` You ll need to delete that reference from the list

microscopic-florist-22719 · Answer

Once the delete is finished you can import the repaired checkpoint using `$ pulumi stack import lt repaired json`

I d recommend saving the original invalid checkpoint just in case of further disaster

it would also be helpful if you can share it with myself or < white balloon 205> via DM

In my case I ran into this when trying to create a RolePolicyAttachment using an `aws iam Role` that I obtained via `aws iam Role get` Since this resource was read it is not in the checkpoint Presumably <https github com pulumi pulumi issues 1521> when fixed will address my case

bitter-oil-46081 · Answer

In my case I was able to recover by exporting the checkpoint with `pulumi stack export` hand editing to remove the bogus URN from the list of dependencies and then import it and run my program again after editing it so I didn t immediately fall into this case again

stocky-spoon-28903 · Answer

Ah that makes sense In this case the offending item was the default route table of a VPC

stocky-spoon-28903 · Answer

I ll try exporting and manually editing the checkpoint
