Terraform Version

Terraform v1.1.3
on darwin_amd64

• provider registry.terraform.io/pagerduty/pagerduty v2.2.1

Affected Resource(s)

Please list the resources as a list, for example:

• pagerduty_ruleset_rule

If this issue appears to affect multiple resources, it may be an issue with Terraform's core, so please mention this.

Debug Output

Panic Output

NA

Expected Behavior

When creating a module to create rulesets, I expect the apply to be successful.

Actual Behavior

Encountering "The plugin encountered an error, and failed to respond to the plugin.(*GRPCProvider).ApplyResourceChange call. The plugin logs may contain more details." error, provider crashes. On PagerDuty side, ruleset gets created, but not individual rules.

Steps to Reproduce

1. Download the configuration files
2. Initiate a terraform repo in the Archive folder.
3. Create / copy PagerDuty API key
4. Run terraform apply, provide the key when prompted.

Important Factoids

Rulesets are managed using a module (contained in ruleset folder of the zip file)

I have also some issues with this version. on multiple resources, it's hard to understand what is going on.
And i cannot revert de provider because I always get "a number is required" on the old provider (v1)

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

This is really random, I have 5000 resources to manage and sometimes it works sometimes it fails. I also tried to run it with -parallelism=1 and still get the same error at some point.

[PitcherIT]

In the original examples @gsreynolds identified the issue being that the provider was crashing because it does not expect null to be passed as a value. Where there is no priority, route, severity or annotation (in the case of the event rule) the provider expects the block to be omitted. Also when setting the priority, you need to provide the priority ID and not the name/summary. HTH

[gsreynolds]

Specifically, the priority, route, severity, or annotation blocks would need to be omitted in a similar manner using dynamic blocks as the linked example Terraform did for extractions and suppress.

On the Priority ID lookup, the following would look up the specified priorities:

locals {
  pagerduty_priorities = toset(["P1", "P2", "P3", "P4", "P5"])
}

data "pagerduty_priority" "priorities" {
  for_each = local.pagerduty_priorities
  name = each.key
}

and thus a priority ID can then be looked up with

data.pagerduty_priority.priorities["P1"].id

or in the example code

data.pagerduty_priority.priorities[actions.value.priority].id
