# 🐞 Bug report: Obscure error while uploading a logo during BUIDL creation

When a logo is being uploaded, the API returns a `400` error:

```json
{"file_name":["Ensure this field has no more than 64 characters."]}
```
However, the user doesn't receive any notification in the user interface. Given that the logo field is mandatory, users may encounter an inability to create a BUIDL, with the reason being unclear.

## 😺 Possible solution

Display the error in the BUIDL creation form.
