TypeError: n[0][n[1].key] is undefined -> Error when create a document w attribute t string array

            xxxyyyy,
            'xxxxxyyyy',
            Appwrite.ID.unique(),
            {               
                variants: ['0']
            },
        );```
document is created, i can see it in console, however when i want to access to its data in console, it dont show anything and crash with this errors:
```Uncaught (in promise) TypeError: n[0][n[1].key] is undefined
Uncaught (in promise) Error: Timeout
Realtime got disconnected. Reconnect will be attempted in 1 seconds. <empty string>```

i cant then use console until i refresh the browser, if i go to collection i can see the document on the documents list but the variants columns only shows [ ] 

if i try to add a document manually from console it add the document too but again, variants attribute shows empty and trying to access to the document data make it crash again

if i delete the attribute variants and try to create it again manually from console it creates the attribute but shows a label "fail" or "failed" when listing the attributes of the collection, i need to delete the database and create it again so i can add the attribute again from scratch.. 

is this a bug or i missing something? Im running 1.4.13 self hosted
