[X] This is a bug with an existing resource and is not a feature request or enhancement. Feature requests should be submitted with Cloudflare Support or your account team.
[X] I have searched the issue tracker and my issue isn't already found.
[X] I have replicated my issue using the latest version of the provider and it is still present.

Error: The terraform-provider-cloudflare_v4.32.0 plugin crashed!

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.

Operation failed: failed running terraform apply (exit 1)

Expected output

Modification of the existing page rules

Actual output

│ Error: Plugin did not respond │ │ The plugin encountered an error, and failed to respond to the │ plugin6.(*GRPCProvider).ApplyResourceChange call. The plugin logs may │ contain more details. ╵

Steps to reproduce

Import an existing Page Rule
Terraform Plan - Should give positive output (added in the gist file)
Terraform apply (using both 4.32 and 4.33) - to get the Panic error.

Additional factoids

There are some mandatory fields in the page rules resource, and that's why, during the plan, they are being added with default values, and I don't get the " Your infrastructure matches the configuration."

jacobbednarz commented 6 months ago

the error you've listed here is not the problem here; it is only a symptom.

Stack trace from the terraform-provider-cloudflare_v4.32.0 plugin:

panic: interface conversion: interface {} is nil, not map[string]interface {}

is the issue. as this is reproduction includes dynamics (and likely includes its own logic bugs), i'm sorry but we can't debug it. if you can reproduce the problem without using them, i'm happy to triage.

Observing similar issue in the latest version of the provider (4.36.0). Works fine in 4.34.0.
