Error de conexión de niebla en el nodo Geth privado

Creé mi red privada y ejecuté mi Geth Node como:

geth --datadir /mychaindata --rpc --rpccorsdomain "*" --nodiscover

Puedo adjuntarlo con éxito y crear una cuenta cuando ejecuto:

geth attach ipc:/mychaindata/geth.ipc

He escrito un contrato inteligente y quiero implementarlo a través de Mist. Descargué el código fuente de Mist, cambié a la rama principal y compilé el código fuente. Cuando ejecuto esto:

yarn dev:electron --rpc /mychaindata/geth.ipc

Comienza con éxito con un error en la línea de comando:

yarn run v1.3.2
$ electron -r babel-register main.js --rpc /mychaindata/geth.ipc
