It return vm_status miscellaneous_error when I use method "get_account_transaction"

When i create my first client,first, i create private key,publick_key,auth_key and address,I use method “mint”, then it error.
I just find when it call “get_account_transaction”, it return right hash data, but vm_status dot type is “miscellaneous_error”
It maybe wrong with server I guess.
How can i resolve this problem
GreateThanks!
