Darksidewalletd does not tell developers why it failed when a method is invoked

[pacu]

What is the bug?
when running zecwallet-cli against darkside mode, it would fail with an unhelpful message

note: this seed phrase is part of darksidewalletd's test datasets. don't use it for anything else than integration tests.
