Hellochain compile problem

Hi, I’m following the hellochain sample instructions and sample code directly from the website, and trying to compile I get:

github.com/cosmos/cosmos-sdk/x/auth/client/utils

…/…/pkg/mod/github.com/cosmos/cosmos-sdk@v0.38.1/x/auth/client/utils/query.go:45:30: not enough arguments in call to node.TxSearch
have (string, bool, int, int)
want (string, bool, int, int, string)
make: *** [install] Error 2

any help appreciated. Still getting up to speed on all this. My guess is the sample app code was for an older SDK version, but i’m not sure how to update it…
