Hi @deian, are we talking about the invoke_sandbox_function ?
Also just to confirm, since we don't actually pass the sandbox as an argument, are we looking for an error when the sandbox is missing, or for the function name that is to be invoked?

Close, but not exactly. We're talking about sandbox_invoke, which expects a sandbox as a the first argument.

Though @shravanrn is the plan to move everything to invoke_sandbox_function?

Actually, we intend to support both going forward. But yes, the error message is not very helpful when the argument is missing.
