I'm not sure if this is correct for detecting a cadence error locally.
Currently, we assume any error from fvm is "InvalidArgument":
flow-go/engine/execution/rpc/engine.go
Lines 194 to 198 in 259992f
it seems like we could do better. I'm ok just leaving the logic the same for now though.

this could fail for a lot of reasons that aren't errors occurring on the node, so I figure it's better to produce fewer error level messages in that case.

can use convertScriptExecutionError here too?

not directly since it has some additional error type handling done in convertScriptExecutionError that doesn't apply to getting accounts, but I could extract the common bits out to a separate function

how does it work that when the height is for past sporks, we query historical AN?

no, it works the same as it does today, except instead of a state commitment not found error, we return data for block height x is not available. The client will need to first check if the height they are querying for is within the current spork

just want to double-check, this state used here is the same state as used by script executor right?

I don't think the script executor uses state directly, just headers. but they are both populated by the follower engine

Is it possible that we don't create the script executor until its dependencies are ready, this eliminates the case where ScriptExecutor's method is called before the indexer and scripts model are passed in.

The challenge is that we want the API to run before the checkpoint loads. So there needs to be some way for the API to check if scripts is available. I used the approach of wrapping it in engine/access/rpc/backend/script_executor.go, but am open to other approaches if you have other ideas.

+1 I've used the same approach for GetRegisterValues
