I query the delegatable bandwidth share through the following command, and it returns empty {}. But the unused bandwidth share is 3TRX, So i need to know why it returns empty or how many unused bandwidth share I need to have so as to wallet/getcandelegatedmaxsize API will not return { }.
curl --request POST \
--url https://api.nileex.io/wallet/getcandelegatedmaxsize \
--header 'accept: application/json' \
--header 'content-type: application/json' \
--data '
