Error: The terraform-provider-snowflake_v0.91.0 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. Cleaning up project directory and file based variables 00:00 ERROR: Job failed: exit code 1

Would you like to implement a fix?

• Yeah, I'll take it 😎

As discussed the workaround for now is to set the "alert_schedule" field. I'll add this issue to our list of bugfixes to resolve during alert resource refactor (here).
