Internal server error with orderBy param

[dated]

Calling the API with unsupported (?) orderBy query params triggers an internal server error,

e.g.

mainnet: https://explorer.ark.io/api/v2/wallets/ALzabhk9wwcA9S8bHxSiUWZ93AGi3mCq3a/transactions?orderBy=sender:asc

devnet: https://dexplorer.ark.io/api/v2/wallets/DNjuJEDQkhrJ7cA9FZ2iVXt5anYiM8Jtc9/transactions?orderBy=sender:asc

Debug: internal, implementation, error 
    TypeError: Cannot read property 'asc' of undefined
    at TransactionsRepository.findManyWithCount (/home/ark/.config/yarn/global/node_modules/@arkecosystem/core-database-postgres/dist/repositories/repository.js:44:54)

    [...]
