Is there any way to rename a SNS topic without having to redeploy everything 😂

I accidentally added an SNS topic name that is not

stage

aware and now that is causing me headaches

I was trying to create a new topic and point all stuff to that new topic and than delete the old one… but I am getting an error like this when I try to do that

Copy code

❌  kujtim-v1-devstride-EventsStack failed: Export kujtim-v1-devstride-EventsStack:ExportsOutputRefDevStrideSnsFiFoTopic321EDAD8F239367B cannot be deleted as it is in use by kujtim-v1-devstride-ItemStack

I had this on the

ItemStack

Copy code

eventStack.snsFiFo.addSubscribers(this, [
      {
        queue:
          fifoItemModuleEventsTarget instanceof sst.Queue
            ? fifoItemModuleEventsTarget
            : undefined,
        function:
          fifoItemModuleEventsTarget instanceof sst.Function
            ? fifoItemModuleEventsTarget
            : undefined,
        subscriberProps: {
          filterPolicy: {
            DetailType: SubscriptionFilter.stringFilter({
              allowlist: [FolderParentChangedFIFOIntegrationEvent.name],
            }),
          },
        },
      },
    ]);

And removed it… You would think after removing this the dependency would be removed also 🤷‍♂️

Hey @Kujtim Hoxha, in the stack you are creating the SNS topic, try adding a manual export of the old topic arn:

Copy code

this.exportValue(oldTopic.topicArn);

This will preserve the old export. You can remove this line after you move over the rest of the app to use the new topic.

Give it a try!

Just as a note, this unintuitive exports functionality and rigidity have caused me never to use them, and I find SSM parameters to be significantly easier and more flexible (and still free). Just letting you know you have options.

Yeah this is very weird behavior, @Frank thanks for the suggestion I think that is working 👍

Alright, starting v0.60.8, SST will handle this automatically by temporarily adding the exports.
