panic: fatal: An assertion has failed: Expected diff to not require deletion or replacement during Update of urn:pulumi:dev::<project>::aws:batch/computeEnvironment:ComputeEnvironment::gpu-worker-computeEnvironment-us-east-1
last night. I destroyed the stack, rebooted, backed out all changes to a point that was definitely working. I don’t know what else to try. Any ideas? A change to an AWS Batch Compute Environment almost always results in a replacement.
I did upgrade my pulumi client and pulumi typescript dependencies just before this started happening.

According to https://github.com/pulumi/pulumi/issues/2914 the bug has been fixed 🤷‍♂️
g
While similar message I think that's a different bug. Do you mind opening a new issue with your info?

e
is there a way to specify that a resource requires replacement?
g
Can you elaborate?

Expected diff to not require deletion or replacement during Update
I figured I could make the error go away if I could tell pulumi to expect replacement and not an incremental update.
actually, maybe 
deleteBeforeReplace
will work
I’ve narrowed down the issue. I’m using multiple providers to deploy AWS Batch Compute Environments to different AWS regions. Batch CEs doesn’t support all EC2 instances types in all regions so 
c3.xlarge
is fine in 
us-west-2
, but not in 
us-east-2
. I’m experimenting with various instance types so I occasionally add one that isn’t supported in all regions. When I do that, pulumi’s state gets screwed up(re: ☝️) and I have to destroy the stack and remove the offending instance type to get things into a good state. recap: • deploy CE with c5, good • deploy CE with c3, c5 - update kicked back with invalid type for us-east-2 • remove c3 and deploy with original c5 - transport error I posted above and no obvious way to recover without destroying everything
g
Oh, that's super helpful.
e
I have to slightly modify my last response. It takes a little fiddling to get it into a bad state, and now it seems to only show the transport error one time after a bad instance is introduced. I’ll keep digging.
g
When you get to a reproducible bit of code, please do open an issue with it. We definitely want to improve this experience, at least with more helpful error messages.
e
Will do
