Error: Cannot read properties of undefined (reading 'map') #5

Hello, my entire dashboard is crashing after installing this package. Here's the stack trace: 

Error: Cannot read properties of undefined (reading 'map')
TypeError: Cannot read properties of undefined (reading 'map')

I suspect it is because I have some non standard list options (for instance the list parameter in my setup accepts promises for list items fetched somewhere else). Would it be possible to add a bit stricter type check on https://github.com/sanity-io/assist/blob/725164766422d2f7ff2b1c82777353ed08b70205/plugin/src/schemas/serialize/serializeSchema.ts#L86C1-L87C1 ? a simple replacement of values: type?.options?.list to values: type?.options?.list?.map or values: typeof type?.options?.list?.map === 'function' should suffice for my needs.

I apologize as I know this is non-standard/unsupported behavior, but hopefully the code change should be small enough and of the type that doesn't really introduce tech debt. Happy to submit a PR myself if that helps.

Hey, sorry about this. Would love a PR, possibly checking for Array.isArray(type?.options?.list) as the guard?

Thank you for the response. I added a PR with a suggested fix now.
