Failed to marshal plan to json: value is not known

[stjohnfinn]

Getting Failed to marshal plan to json: value is not known when I plan and the plan just completely stops there and it doesn't show N to create, N to change, N to delete, so it kind of makes the provider unusable. I don't think it's an issue with my code because I'm not doing anything weird or complex and I've had Claude starting at it for a couple hours. I think it's something with computed values....maybe the ID of these resources? but computed values don't break plans as far as I know. EC2 instance IDs are post-apply computed values and they don't break the plan.

Not really sure what's going on. I would love to use this provider but I can't really use it with this bug.
