+resource/cloudflare_api_shield_operation: fixed a bug when using variable names other than `var1 ... varN` in endpoint definitions causing these resources to be recreated when nothing has changed.
+If this affects you, after upgrading to this version, the resource has to be recreated once more to fix the state, after which the bug is fixed.
