Error: The terraform-provider-launchdarkly_v2.12.0 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.`

Oh interesting - do you have a snippet of your Terraform manifest we can use to reproduce? Probably just the feature_flag resource.

Hi @mohamaa ! I hope you managed to get past this, but it is due to the definition of an empty fallthrough block. Also, your configuration will fail again because the off_variation index exceeds the number of variations defined on the flag - we do not backfill extra variations without explicit definition.

Nonetheless, panicking is definitely not a desired behavior and we will consider this a bug in the provider to be fixed ASAP. Thank you for bringing this to our attention!
