Vue array undefined

I recently work on my team project that uses vue3. I am still trying to get used to vue component and api, so please excuse me for asking such a simple question. I was working on this page where I was supposed to filter objects out of an array that I computed the data (using the computed method) and use the data info in another function called filterItem. Before I use the function filterItem, everything in the data (issue) worked fine as I console logged the object, but when I passed the data in the function and parsed the array, I got an undefined array. But if do a small edit (like a space) and save the file then the local server would rebuild and rerun the server then I would see all of the objects in the array (issue.value), I was wondering why this happen and is there a way to work around this?

start local server

small edit in code and save, local server rebuild with this
