fix: (UNSURE) ERR_INVALID_STATE

Browse Source 
Stream controller in the endpoint that streams files from the S3 bucket
would ocassionally crash the server by throwing `TypeError
[ERR_INVALID_STATE]: Invalid state: Controller is already closed`. This
should fix that, but as the conditions that cause it to happen are
unknown, this is not certain.
