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

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.

The checkpoint is exported as JSON, so I usually do something like

$ pulumi stack export > d.json

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.

Once the delete is finished, you can import the repaired checkpoint using

$ pulumi stack import < 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)

cc @bitter-oil-46081 who has hit this recently and may also be able to help

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.

I’ll try exporting and manually editing the checkpoint
